I definitely agree with that...

Ahmed,

I agree that Option 1 is a subset of Option 2. However Option 1 tackles the specific case when no domain ontology is involved.

However, we can just use two images (Option 2 and Option 3) and explicitly state that in Option 2 there is a possibility of just generating the Local Ontology and not involving the domain ontology. That is fine by me.

What does everybody else think?

Juan,

It sounds like the three options images are the same image?

I missed the last meeting and what was discussed.  In your list, Option-1 is a special case of Option-2; I questions its value but we can leave it as a special case of Option-2 in your current list.

I suggest:


1.       Local Ontology mapping + local-to-domain Ontology mapping

*         Local Ontology mapping only (option)

2.       DB Schema to Domain ontology direct mapping

If you look at many current products they typically use option-1 above.

Subject: Images of RDB2RDF options updated

Hi Everybody

Ted and I have updated the images that depict the three different RDB2RDF options.

[1] Option 1: Direct Mapping (no domain ontology involved
[2] Option 2: Direct Mapping + Ontology to Ontology Mapping
[3] Option 3: Database to Ontology Mapping (no visible local ontology

Please note that the current Option 3 was the old Option 2 (and vice-versa)

Let me know if there are questions

Cheers
