Re: [geogig-dev] GeoGig upload endpoint
Hey Victor, all, cc'ing the devel list, lets try to send tech discussions over there as much as possible, disregard most of them being held on slack/gerrit.

JD's took over GIG-155.

The way it works is by calling POST <repo end point>/import?format=gpkg&... and sending the file as a POST form field called "fileUpload". Check the "Import GeoPackage" feature report here http://dev.boundlessgeo.com/~groldan/cucumber-report/

When importing a geopackage with the geogig extension and populated audit tables, the only difference is you'll have to add the "interchange=true" argument to the URL.

That said, JD's working out the details and I anticipate we'll have to:
a- extend the op to indicate on top of which branch to import
b- better define the op's return value (report) to make sure the client can put the local geopackage in a state that's in sync with the resulting commit on the server.

but we're making progress, lets sync'up when you're back from vacation.

Erik, Gabriel

I didnt have time to look at this, but want to resume it once I am back from vacation. 

I see that there is no option for now to use the audit tables. Do you think it is better to wait until that is solved, or I should adapt the mechanism to work with this limitation and upload the full table?

Please, let me know the current state, so I can have all the info to continue working on this.

Thanks!

Hey Voctor,

Yes, Gabriel merged the import functionality over the past weekend. It's working, but it has a couple of limitations (unless Gabriel fixed them that I don't know about).

1) When you import, it will add the geopackage data to the current working branch (there isn't a way to specify which branch you want to import into)
2) Import of Geopkg data doesn't support reading from audit tables in the geopkg file to be imported. It just adds the data it finds in the imported geopkg.

To use it, you must POST a request to the service. The most basic way is something like this (for XML responses):

POST <repository URL>/import?format=gpkg

or if you want JSON responses:

POST <repository URL>/import.json?format=gpkg

and the generic API is this:

POST <repository URL>/import[.xml|.json]?format=<format name>[&layer=<layer table name>][&dest=<destination path][&alter=<true|false>][&forceFeatureType=<true|false>][&fidAaaattribute=<attribute name>][&authorEmail=<email address>][&authorName=<author name>][&message=<commit message>]

You MUST include the file to import in the request body, named "fileUpload", encoded as a multi-part content (see the Postman screenshot below).


​
You can add the "authorName", "authorEmail" and "message" request parameters too if you want to set them for the commit.

Let me know if you need more.

Hey Erik

I have seen that there is already an endpoint to upload/import a layer
to a geogig repo. Is that working fine already?

I am back working on the geogig QGIS plugin, and that's a
functionality that i have to implement. Could you give me some example
of using that endpoint (a curl example would be fine) and whatever
extra info i need to be able to use it from QGIS?

thanks!
