The HGG term was
designed to dovetail with TimBL’s thoughts on the giant global graph (GGG)
here: http://dig.csail.mit.edu/breadcrumbs/node/215
and here: http://en.wikipedia.org/wiki/Linked_Data
(LD)
The Higgins 1.1 global graph encompasses all of the
nodes in Tim’s GGG and LD by embracing at least one of the two forms of
Linked Data HTTP URIs. The HGG 1.1, however, can go much further because thanks
to the HGG’s UDIs, XRDS, IdAS, and Context Providers its is possible to also
encompass into one seamless HGG data from legacy data stores like LDAP
directories, RDB data sources, etc. –and even access them using their
NATIVE protocols (e.g. SQL, LDAP, etc.).

[higgins-dev] I've
updated the HGG wiki and PPT
|
Jim,
The wiki
pages rooted at [1] have now been updated per Higgins
1.1 in three ways. First, the sub-pages all have (or should have) a
“Version” section at the top. Second I have eliminated the 1.0
concept of Entity and changed zillions of places where Node was to now read
Entity. Finally, I’ve update a few of them per our decision to simply use
Entities as complex values. I have also edited the PPT here [2] per the latest
HGG 1.1 model.
I also
renamed “Higgins
Identifier” to “UDI” and expanded its coverage from HTTP URIs
and XRIs to also include support for the semweb community’s “Linked
Data” HTTP URIs. We haven’t yet implemented support for Linked Data
URIs but I think that doing so would allow Higgins
IdAS to be used as a gateway to at least some of the emerging Linked Data data
sources. Parity will be contributing resources to implement this stuff. It will
help the IdAS/Higgins cause WRT both
the partially overlapping semweb and the dataportability crowds.
