Framework evaluation - Is stardog right for me?

[ben...@gmail.com]

Hello everyone!

I'm currently evaluating Frameworks which would allow OBDA. I'm not sure if stardog can be used for that and where to start.

The solution should be capable of the following things:

Reasoning over an OWL Ontology where several concepts are described. Those concepts are then mapped to datasources (word, excel, sharepoint in my case). And the system would then be able to answer SPARQL queries on the ontology with data from the sources. Sth. like: "give me all the cars from 1950" and it would then consult an excel list with the cars and return them.

It would be really helpful if you could give me some hints and opinions from your perspective on this matter. I know there are OBDA frameworks like Ontop which are capable of this, but I want to evaluate thoroughly and consider every option. 

Thanks a lot for your time!

Hi,

Is this for commercial or research/academic purposes? Stardog is in fact an OBDA system built into a fast graph database.

Cheers,

Kendall

it is academic/research. As of now I want to develop a proof-of-concept and then build upon this.

Stardog seems promising, do you have some sort of academic paper which explains some of the details of stardog? Like: used reasoner, supported standards (mapping, ontology syntax)

We have pretty extensive documentation online [1].

Oh, I see sorry about that!

Stardog is for commercial use. You can use the Community edition for academic research.

ok, thanks. But in general I should be able to achieve exactly what I want with Stardog, right?

Is it possible to add Teiid (as a federationsystem) to stardog (it offers a JDBC driver)? Or is it possible to write my own "connectors" to datasources such as Word/Excel?

I really think that stardog could be the way to go, but I'm not sure yet. Unfortunately I only have ~20 days for implementation, so I don't have the time to try each and every framework in depth.

Unless you've had a side conversation I don't think you've mentioned what you're looking to achieve.

Im not familiar with Teiid but just a jdbc driver probably isn't going to be enough. I'm not sure how connecting to Word would work but for Excel you can export to csv and use Stardog to map and import the data.

Looks like it might be possible. I'll let the Stardog people weigh in on if it's possible through Stardog.
