Last revised 9 December, 2005
marks interesting changes since the previous draft of 28 September, 2005
This document lays out the feature and API set for the next feature release of the Eclipse BIRT project after 1.0.1, designated release 2.0.
- Release deliverables
- Release milestones
- Target operating environments
- Compatibility with previous releases
Plans do not materialize out of nowhere, nor are they entirely static. To ensure the planning process is transparent and open to the entire Eclipse community, plans are posted in an embryonic form and then revised from time to time throughout the release cycle.
The first part of the plan deals with the important matters of release deliverables, release milestones, target operating environments, and release-to-release compatibility. These are all things that need to be clear for any release, even if no features were to change.
The remainder of the plan consists of plan items for the projects under the Eclipse BIRT project. Each plan item covers a feature or API that is to be added, or some aspect that is to be improved. Each plan item has its own entry in the Eclipse bugzilla database, with a title and a concise summary (usually a single paragraph) that explains the work item at a suitably high enough level so that everyone can readily understand what the work item is without having to understand the nitty-gritty detail.
Please send comments about this draft plan to the BIRT Developer mailing list.
The release deliverables are:
- Source code release for Eclipse BIRT, available as versions tagged "R2.0" in the eclipse.org CVS repository.
- Eclipse BIRT Report Framework 2.0.
- Eclipse BIRT RCP Report Designer 2.0.
- Eclipse BIRT Runtime 2.0
- Eclipse BIRT Charts 2.0
- Eclipse BIRT Test Suites 2.0
The Eclipse BIRT 2.0 release is targeted for release on December 30th 2005, pending community release review. All release deliverables will be available for download as soon as the release has been tested and validated in the target operating configurations listed below.
- Friday, September 16, 2005 BIRT 2.0 M1
- Monday, October 24, 2005 BIRT 2.0 M2
- Monday, November 21, 2005 BIRT 2.0 M3
- Friday, December 30, 2005 BIRT 2.0 Release Candidate
- Friday, January 20, 2006 BIRT 2.0
For information about new features assigned to each milestone please refer to the bugzilla database. The bugzilla database will be updated on an ongoing basis as the plan progresses.
In order to remain current, each release of an Eclipse project targets reasonably current versions of underlying operating environments and other Eclipse projects on which it depends.
Most of Eclipse, and all of BIRT, is “pure” Java™ code and has no direct dependence on the underlying operating system. For BIRT, the chief dependence is on the Eclipse Platform, Graphical Editor Framework (GEF), Modeling Framework (EMF), and on the Java 2 Platform that runs it.
The Eclipse BIRT 2.0 release depends on the following compatibility stack:BIRT 2.0 Reference Stack for Eclipse 3.1
- Java 2 platform Java Development Kit (JDK) 1.4.2
- Eclipse Platform Runtime Binary 3.1
- Graphical Editor Framework (GEF) Runtime 3.1
- Eclipse Modeling Framework (EMF) 2.1.0
The Eclipse Platform and BIRT run in a variety of operating environments. Testing is focused on a handful of popular combinations of operating system and Java 2 Platform; these are our reference platforms. Eclipse BIRT undoubtedly runs fine in many operating environments beyond the reference platforms we test. However, since we do not systematically test them we cannot vouch for them. Problems encountered when running Eclipse BIRT on non-reference platforms that cannot be recreated on any reference platform will be given lower priority than problems with running Eclipse BIRT on a reference platform.
For BIRT 2.0, the project team plans to tests and validate the following reference platforms:

Eclipse is designed as the basis for internationalized products. The user interface elements provided by the various Eclipse projects, including dialogs and error messages, are externalized. The English strings for BIRT are provided as the default resource bundles. Translations are provided with this release for French (fr_FR), German (de_DE), Spanish (es_ES), Japanese (ja_JP), Simplified Chinese (zh_CN), and Korean (ko_KR).
BIRT 2.0 will be compatible with earlier versions of BIRT to the greatest extent possible. The nature and scope of some of the key plan items for BIRT 2.0 are such that the only feasible solutions might break compatibility. In other regards, BIRT 2.0 will be compatible with 1.0.1 and 1.0. We also aim to minimize the effort required to port an existing plug-in to the 2.0 APIs.
Compatibility of Release 2.0 with 1.x
BIRT 2.0 will be compatible with BIRT 1.x unless noted. The detailed compatibility statement is listed below. In this statement, "BIRT" refers to all BIRT components: BIRT Report Framework, BIRT Runtime, and BIRT Chart SDK.
API Contract Compatibility: BIRT 2.0 will be upwards contract-compatible with BIRT 1.x to the greatest extent possible. All incompatibility exceptions will be documented. Downward contract compatibility is not supported. There is no guarantee that compliance with BIRT 2.0 APIs will ensure compliance with BIRT 1.x APIs. Refer to general Eclipse document on Evolving APIs for a discussion of the kinds of API changes that maintain contract compatibility.
The BIRT Chart UI API v2.0 is not compatible with the v1.0 API due to a full redesign of the Chart UI. However, older extension implementations are expected to be used with the new version as noted below –Support for Old Chart UI Extension Points
‘uisheets’ Extension Point: The ‘uisheets’ extension point will be supported but in a slightly limited form. It will be used to populate the navigation tree in the formatting task sheet only. All extensions will be displayed under a special ‘Custom Properties’ node of the tree. The structure of the nodes represented by the extensions will be maintained.
‘types’ Extension Point: This extension point will be supported with some new functionality added to the interface. If the existing extension is created by implementing the interface, it will need to be modified to implement the additional methods. If it extends the default implementation, no changes will be needed. It will still be suggested that the new functionality be reviewed so that its relevance to each extension can be examined.
‘changelisteners’ Extension Point: This extension point will NOT be supported. The functionality that could be extended and controlled using this extension point will not be available in the new User Interface.
‘seriescomposites’ Extension Point: This extension point will be supported and will have the same use as it did in version 1.0 viz. to provide UI components to set attribute and data properties for custom series types. The location and use of these custom composites however will be a little different in the new UI. In this case, the data composite will be used in the data screen to allow setting of the data definition for the series components. The attribute composite will be used in the advanced popup for the series.
Binary (plug-in) Compatibility: The BIRT 2.0 plug-in framework will be upwards binary-compatible with BIRT 1.x plug-ins to the greatest extent possible. Downward plug-in compatibility is not supported. Plug-ins for BIRT 2.0 will not be usable in BIRT 1.x. Extension plug-ins for BIRT 1.x will be upwards binary-compatible with BIRT 2.0.
Source Compatibility: BIRT 2.0 will be upwards source-compatible with BIRT 1.x to the greatest extent possible. This means that source files written to use BIRT 1.x APIs will successfully compile and run against BIRT 2.0 APIs. Downward source compatibility is not supported. If source files use new BIRT APIs, they will not be usable with an earlier version of BIRT.
Report Design Compatibility:BIRT 2.0 will be upwards report design compatible with BIRT 1.x unless noted. This means that reports created with BIRT 1.x can be successfully opened by BIRT 2.0 and upgraded to a 2.0 format.
Non-compliant usage of API's: All non-API methods and classes, and certainly everything in a package with "internal" in its name, are considered implementation details which may vary between operating environment and are subject to change without notice. Client plug-ins that directly depend on anything other than what is specified in the BIRT API are inherently unsupportable and receive no guarantees about compatibility within a single release much less with an earlier releases.
Continuing on the theme for BIRT 1.x, the BIRT project's overriding release 2.0 theme remains extending the Eclipse platform to provide infrastructure and tools that allow application developers to design, deploy, generate and view reports within their applications. In this context, the BIRT project also adopts and supports key themes within the overall Eclipse planning process.
- Scaling Up - BIRT 2.0 targets the needs of report developers who report on large datasets generating large report documents with thousands of pages. This release also provides the capability to store report documents persistently.
- Design for Extensibility - BIRT 2.0 extends the extension points in the BIRT framework by implementing additional extensions on the framework. Some examples include support for XML as an additional data source and support for templates.
- Simple to Use - BIRT 2.0 includes a number of enhancements in this area such as scripting using Java, enhanced charting wizard functionality, improvements to the expression builder, and ease of use enhancements to the ROM API. Additionally, BIRT 2.0 continues to provide the RCP based report designer which is targeted at the report developer.
- Appeal to a Broader Community - BIRT 2.0 will broaden the appeal of BIRT by enabling additional applications of BIRT technology. This will be made possible by the availability of support for numerous additional types of reports.
Report Types, Layouts, and Controls
Multi-pass Aggregate, Sorting and Filtering Some queries require multiple passes over the data. For example, a report may wish to display a listing of top deals. The entry in the report for each deal might show the size of the deal as a percentage of the total sales for that quarter. Such “two-pass” aggregates require BIRT to make one pass over the data to compute the total for the quarter, then a second pass to generate the report. This multi-pass aggregation is not supported by all data sources. This project therefore extends BIRT to provide support for multi-pass aggregates for all data sources. [Bugzilla ID: 110640][Theme: Simple to use, Appeal to a Broader Community]
Top N / Bottom N Report Layout Top N / Bottom N reports display information that is typically sorted by an aggregated number, for example, a report that lists the top 3 performing sales people. This project will provide capabilities to easily create a Top N / Bottom N type report section. [Bugzilla ID: 110641][Theme: Simple to use]
Provide support for binding Blob/Clob data to report controls Many database schemas, such as those used for call center or customer support applications, contain columns defined as character large objects (CLOBs). These fields contain, for example, the variable length and free format text notes that the call center representative takes when speaking to a customer. In addition, an human resources system might store pictures of employees in a database as binary large objects (BLOBS). This project will provide easy support for displaying BLOBS/CLOBs in a BIRT report. [Bugzilla ID: 110642][Theme: Simple to use, Appeal to a Broader Community]
BIRT Java Script Objects
Interactive Report Viewing
Page-on-Demand Navigation Page-on-demand is a mechanism for dealing efficiently with large report documents over a remote connection such as to the internet. Instead of reading an entire report into memory or sending an entire report over a network, pages are requested by the application and sent as needed. This method of data transfer improves response time for the end user and optimizes resource usage. When integrating BIRT into applications, particularly web applications, page-on-demand capabilities are needed to ensure that the application can be built with acceptable performance. This feature consists of two projects: 1) providing the application developer with page-on-demand viewing API’s. [Bugzilla ID: 110645] 2) including an exemplary implementation of a viewing framework that allows application developers to easily integrate viewing functionality into their applications and customize the viewing capabilities they choose. [Bugzilla ID: 110646] [Theme: Scaling up]
Report Paging Long reports need to be divided into pages for effective use. This division can occur either automatically, or with specific page breaks determined by the report developer. Multi-page report support will allow the report developer to design reports that have controlled page breaks (such as for each new group value), or using automatic page breaks, and for the application developer to integrate page navigation of BIRT reports into the application itself. The definition of a page in this context needs to be flexible to accommodate differing physical characteristics, or logical constructs such as a page for each customer. This project enables BIRT to support multi-page report output. [Bugzilla ID: 110671] [Theme: Scaling up]
Hyperlinks to Other Reports This project provides the report developer the capability to link easily to another report while not hard wiring the report to a particular environment. Additionally, if a user navigates to another report, it also provides the mechanisms to retain the state of the original report. [Bugzilla ID: 110648] [Theme: Simple to use]
Bookmarks (Hyperlinks into a Report Body) It is often desirable to hyperlink into a specific point in a report document, for example, to a chart that has sales summaries for the Western Region. Many report items can be the target of hyperlinks. The BIRT bookmark feature is a string that uniquely identifies the item instance within the report. This project provides support for the bookmark concept in BIRT reports. [Bugzilla ID: 110651] [Theme: Simple to use]
Table of Contents Support in Viewer A table of contents shows the hierarchical structure of a report to the end user and allows the user to easily and quickly navigate to sections of the report. The hierarchy is defined by the report grouping and sub report structure, with customizations possible by the report developer, such as providing custom text for each node in the hierarchy. TOC features include: ability to expand the TOC one level at a time, handle arbitrarily large groups at any node/level in the hierarchy, and links from the group title jump to the first page of that group. Note that this project is focused on TOC as a navigational mechanism in the report viewer, rather than providing a TOC element that can be embedded in a report. This later item is a separate feature that is not scheduled for this release. [Bugzilla ID: 110655] [Theme: Simple to use]
Report Engine Scalability and Performance
Memory Usage Efficiency Improvement This project intends to enhance the BIRT engine to utilize memory more efficiently. [Bugzilla ID: 110656] [Theme: Scaling up]
Concurrent User Scalability Large Numbers of Active Users When BIRT is deployed in a production environment with various kinds of application servers, it is expected that there will be hundreds of users who concurrently need to run a BIRT report. BIRT needs to be able to scale to handle running reports concurrently for large numbers of users. [Bugzilla ID: 110658][Theme: Scaling up]
Data Engine Scalability and Performance
Disk-Based Sorting and Data Manipulation Reports against large data sets with millions of rows often require the report engine to sort the data and perform aggregation. To support these scenarios, this project incorporates a sorting and aggregation capability within the BIRT Engine, which, due to the potentially large data sets, can use a combination of memory and disk for the task. [Bugzilla ID: 110659] [Theme: Scaling up]
Cache Query Results while Developing While designing a report, the developer specifies a data set to report on. If the number of records in the data set is large, then the iterative process of making changes to a report followed by previewing those changes slows down because the large data set has to be fetched for each preview operation. This slowdown can hinder quick report design and adversely affect the developer experience and productivity associated with BIRT. This project allows a report developer to specify a property on a data set that limits the number of records that are fetched during the development process, and that those results are cached as much as possible. [Bugzilla ID: 110660][Theme: Simple to use]
Persistent Storage of Report Output It is often desirable to run a report and then store the results of that report for viewing later. For example, generating a large (1000s of pages) report and then viewing pages individually as needed. To support this scenario, this project extends BIRT to offer a way to persistently save a report for viewing at some point in the future. [Bugzilla ID: 110661][Theme: Scaling up]
Improved PDF Output Generation
Robust PDF generation is a key component for reporting since many users generate PDF versions of the report for portability, printing and distribution. For BIRT, the PDF support needs to be very high quality. This project addresses issues related to PDF generation using FOP such as slow performance, limited support for lines and borders, and others. [Bugzilla ID: 120143][Theme: Scaling up]
When creating a new report, BIRT provides the ability to select a template for the report design. With BIRT 1.0, these templates are from a predefined list that is built into the user interface. In order to support context specific uses of BIRT, the application developer wants to be able to add new templates into the user interface. In addition, BIRT will allow templates to be added to the user interface, and for cheat sheets to be associated with the template. It will also be possible to include associations to a style sheet and/or library with the template design. This would allow the developer to provide the person consuming the template with pre-defined styles and/or visual components from a library. [Bugzilla ID: 110662][Theme: Design for extensibility]
Libraries contain report components or functions for reuse in multiple report designs. A report or library developer creates a library, then places it in a shared location for others to use. Libraries improve developer productivity and promote report design consistency, and maintainability. This project will provide library support within BIRT. This includes simple components and compound compounds such as a page header with a logo and address. [Bugzilla ID: 110663] [Theme: Simple to use]
BIRT Style and CSS Style Sheet
External Style Sheets for Use Across Multiple Report Designs This project extends the concept of styles to allow the definition of a style to be contained in a separate style sheet file that can be shared across multiple reports. This will make it easy to establish a common look across all the reports in an application, and if needed, to be able to quickly change the look across many reports just by editing the style sheet. [Bugzilla ID: 110746] [Theme: Scaling up, Simple to use]
Ability to import CSS Style Sheets When designing a report that is going to be deployed in a corporate application, the developer of the report should not have to recreate the styles that have already been defined for the look and feel of the web site. This project allows the BIRT report developer to "point" to an existing CSS style sheet file and import this for use within their report design to define various elements of the report such as fonts, colors, and others. A future project will look at using a CSS style sheet directly without the need to import. [Bugzilla ID: 110664] [Theme: Simple to use]
Code Editor for BIRT Scripting
BIRT supports the ability to script, or code, the behavior of reports in a number of ways. To improve code editing, BIRT will leverage an Eclipse perspective for working with code in BIRT. Perspectives exploit the power of Eclipse to the report designer’s benefit. In addition, they are a way to provide rich functionality by leveraging the Eclipse environment. This project will provide support for and a perspective for Java Code Editing for BIRT reports. [Bugzilla ID: 110665] [Theme: Simple to use]
Dynamic Parameter Selection List
Parameterized BIRT reports can be used to provide a highly personalized experience. End-users can choose to view the information that matters most to them when they want to see it. Parameter values change as quickly as the business itself. For example, a sales manager may want to view total sales closed by a particular salesperson. In order to support the more complex scenario, BIRT should allow report developers to specify that the list of values for a parameter be dynamically populated at run time. The goal of this project is to provide built-in support for dynamic parameters. [Bugzilla ID: 110666] [Theme: Simple to use]
Cascading Dynamic Parameter Lists
Parameterized BIRT reports can be used to provide a highly personalized experience. Building on the support for Dynamic Parameter Lists, a report may require an end user, at run time, to specify more than 1 parameter that are cascaded together. For example, a regional sales report may require the user to specify parameters for the State and City. Suppose the user selects California for the state. The user may then want to see the sales information for a specific city. The user would then specify a value for the City parameter of the report. However, the values for the City parameter list would depend on the value selected for the State parameter and would dynamically at run time be populated with cities in California. This project concerns itself with providing the report developer with the ability to define dynamic parameters that are cascaded together as described above. [Bugzilla ID: 120145][Theme: Simple to use]
Chart Builder and Wizard
BIRT includes support for including charts within a report design. The goal for this project is to improve the usability of the chart control. We will be looking at both a Wizard/Builder approach for common usage/charts, in addition to a more advanced capability for report developers who want to control the chart in more detail. [Bugzilla ID: 110667] [Theme: Simple to use]
Property Editor for Chart Report Item
BIRT provides a Property Editor for accessing commonly used properties for visual and non-visual components in a report. The Property Editor is not currently available for elements in a chart within a report design. For consistency and developer productivity reasons, this project aims to allow the Property Editor to be used for commonly changed properties in a chart. [Bugzilla ID: 110668] [Theme: Simple to use]
Chart component improvements
This project looks at the charting component of BIRT to make a number of significant improvements in chart specification and generation. Examples of improvements to be made include, the ability to use report styles in charts, handling the situation when labels on the X-axis overlap, specifying a legend title, or marker shapes. [Bugzilla ID: 110669] [Theme: Simple to use]
Scripting of Charts
Some Report developers will want to customize the behavior of a chart in a report to meet specific needs requested by their end users. For example, to highlight specific visual elements in a chart based on data values such as expanding the pie slice for the median data value. This project will provide the ability within BIRT to control the behavior of a chart with methods on the chart control. [Bugzilla ID: 110670] [Theme: Simple to use]
With the Expression Builder in BIRT 1.0, it is awkward to build the expression using the user interface. There are a number of improvements that can be made to make it easier to navigate around the functions, and to provide the user with help on each of the functions that are available. This project implements those usability improvements. [Bugzilla ID: 110672] [Theme: Simple to use]
View/Edit XML Report Designs
For developers working with report designs visually in the Layout View, it is useful to be able to see the XML associated with the report design they are working on. With BIRT 1.0, it is only possible to see the XML report design if you close the visual editor and open the design file in the Eclipse XML editor. In BIRT 1.0, it was not possible to easily switch between the visual and XML view. This project provides a mechanism for the report developer to easily switch between the visual and XML views of a report design, and to be able to edit the report in either view.[Bugzilla ID: 120923][Theme: Simple to use]
XML Data Sources
With the rapid adoption of XML as the lingua franca for business information exchange, and for the exchange of information within an application, a large number of developers would like to report against XML data sources. Additionally, most ERP and CRM applications now provide interfaces to deliver data in XML. This project provides an out of the box adapter to access XML data sources. This can be used "as is" or as an example ODA connector that can be adapted for other purposes. [Bugzilla ID: 110763] [Theme: Simple to use, Appeal to a Broader Community]
Certain data sources, such as those accessing data in RDBMS's, support the concept of stored procedures and functions. These constructs provide the capability to pass in parameters as well as pass out resulting data values. This project concerns itself with building the capability to access the output parameters from these types of constructs via BIRT scripting capability. [Bugzilla ID: 110765] [Theme: Simple to use, Appeal to a Broader Community]
Report Object Model API
The BIRT Design Engine API allows developers to programmatically manipulate a report design using an API, rather than manipulating the XML directly. This API was introduced in BIRT 1.0 and is used extensively within the BIRT project itself. This project makes some enhancements to the Design Engine API based on feedback from the community and the BIRT project’s own use of the API. [Bugzilla ID: 110676] [Theme: Design for extensibility]
ODA framework migration to DTP
Move ODA Runtime Extension Point and Java Interfaces to DTP The ODA Runtime Extension Point and Java Interface components will be part of the Eclipse Data Tools Project (DTP) going forward. This BIRT project will move these components from the BIRT areas of Eclipse to DTP and make any naming changes as needed. This includes reviewing and removing any BIRT project dependency and allowing this to use the DTP project instead. The BIRT project team members originally working on this component will continue to work on this project within the DTP project. [Bugzilla ID: 110677] [Theme: Design for extensibility]
Provide Plug-in Adapter for BIRT ODA Drivers to DTP ODA The ODA Runtime Extension Point and Java Interface components will be part of the Eclipse Data Tools Project (DTP) going forward. All ODA Consumer applications are expected to upgrade and adopt the DTP ODA framework and namespace in lieu of the BIRT ODA namespace. For compatibility with existing adapters, this project will provide a plug-in adapter for BIRT ODA drivers that implement the BIRT ODA 2.0.x interfaces. This will allow a DTP ODA consumer application to consume existing BIRT ODA data providers without any source code or binary build changes. However, if an ODA data provider wants to implement any of the enhancements added to ODA version 3.0 or later, its implementation must migrate and adopt the DTP ODA interfaces. [Bugzilla ID: 110678] [Theme: Design for extensibility]
Export Report Data
Data Extraction from a Saved Report This project supports data extraction from a report at several different levels: 1) Report level 2) Dataset level 3) Report item level for a table, list, or chart items 4) Report item instance. Extraction at the report level can be achieved by repeatedly retrieving data for each dataset. Extraction at the report item instance level would include computed columns as normal columns. [Bugzilla ID: 110679] [Theme: Simple to use, Appeal to a Broader Community]
Ability to Export Report Data as CSV Building on the infrastructure of exporting data from a report, this project allows the end user to extract report data as a CSV formatted file. [Bugzilla ID: 110680] [Theme: Simple to use, Appeal to a Broader Community]
Pass-through of external context objects
The BIRT engine is often embedded as part of a middle-tier application server, where the BIRT components are added to the mix of various Java EE components. During report run-time, some of these other components may instantiate context objects, which are served to the BIRT engine for its custom data source to use. The BIRT engine will thus need to pass through such external Java objects into the BIRT data source components for consumption. These context objects are assumed to be dynamically instantiated at report run-time, and are not statically defined in a report design. The scope of this project thus focuses on data source specific run-time Java objects which are instantiated external to BIRT, and are passed through to a custom data source provider plugged in the BIRT engine. Some examples of the types of external context objects that may be passed through to a BIRT data source provider include, an open JDBC connection, a pooled connection, user authorization keys, or query parameter values collected outside of BIRT.
