Right, but is that feasible in practice? Do people actually successfully do that, on a large scale? Or does it run into:
- Having to create your own mapping for every piece of data of every divergent data source, with a not-insignificant amount of work involved?
- Those mappings inevitably containing mistakes/different interpretations that result in invalid data?
- Some of the data not being amenable to lossless mapping in the first place?
In other words: is "RDF provides a solution for that" not overselling it a bit?
- emmanueloga_ 6y agoIf you are asking if RDF provides a silver bullet to integrate data sources, the answer is no, everything requires effort. But I think the integration story is way better than when integrating other data models, say, relational databases. The other aspect is that URLs being the ids for statements, I can peek at the implementation of a 3rd party data model and use that _in advance_, instead of integrating later. For instance, when I write my blog I can use the URLs of existing wikidata entities to model my own entities. If wikipedia entities used a relational model, the IDs of these entities would be opaque and could change at any time, so I wouldn't be able to do that.
