core additions
July 4th, 2003, by Rich.
An addition to the core today is the ability to load RDF from a URI as well as a file - to demonstrate this I now have a news feed from theregister.co.uk being pulled in to the system when it’s started.
This highlights an interesting question. How best should these multiple sources of information be stored and categorised internally - it’s not enough to say that a URI defines where it’s from, because multiple sources may define the same URI, and the properties they define for it combine when unioned.
I can see two possibilities for the RDFX Core:
- Maintain a hashtable of differnt models, passing requests to all of them as necessary and aggregating the results. This has the advantage that serialising those models will be easy.
- Somehow annotate each property as it is loaded by setting it as a property of another Resource whose type is the as-yet-undefined PropertyOrigin - this would have the advantage that the annotation could be browsed in the UI like any other node.
