RDF
RDF List Implementations
...
- It appears that ActiveFedora v8 (Fedora 4) uses ActiveTriples for handling of RDF. Need to look at ActiveFedora code to confirm.
- SOLR integration appears to be done in ActiveFedora, not ActiveTriples. It will likely take a significant effort to move the SOLR integration out of ActiveFedora and into ActiveTriples. Need to look at ActiveFedora code to make an estimate.
- Hydra community is looking at putting RDF Access Control into ActiveFedora and thus Fedora, which complicates (to say the least) the removal of Fedora from the Hydra stack.
- See also Linked Vocabs - Linked Data Controlled Vocabularies for ActiveFedora::RDF
- See also DPLA Map - DPLA's Metadata Application Profile modeled in Active Triples which includes property validation similar to that used in ActiveModel.
- Fetch - ActiveTriples currently has the ability to fetch external data. Demonstrated fetching geo data. This could be cool to exploit.
