Bridge to relational
databases
-
Most of the data on the Web are stored in relational
databases
-
- “RDFying” them is not possible
- relational databases are here to stay…
-
“Bridges” are being defined:
-
- a layer between RDF and the relational data
-
- RDB tables are “mapped” to RDF graphs, possibly on the fly
- different mapping approaches are being used
- this is what our examples did…
- a number RDB systems offer this facility already (eg, Oracle,
OpenLink, …)
-
Work for a survey of mapping techniques has started at W3C
