Re: [HACKERS] deductive databases in postgreSQL

Yes it's an option, but you cannot rely on the typical consulting company to
do that. Do you know any specialized consulting boutique or individual
developer that could do that?

 You could also possibly pay a consulting company to implement it, but even
 that isn't as easy as it may sound. :)

[HACKERS] deductive databases in postgreSQL

[Carlos Gonzalez-Cadenas]

Hi all,

We're looking for a deductive database for our application. Oracle, in the
11g version, has extended its RDBMS with deductive capabilities, supporting
a subset of OWL-DL[1]. They are able to load an ontology, perform the
inferences, dump the inferred info in the database and after that answer
queries with the asserted plus the inferred info.

We would like to have similar functionalities in PostgreSQL. Do you know if
there's someone working on that or if there are plans to support it soon?.
If not, what do you think is the best and most efficient way of implementing
it?

Thank you very much in advance,

Carlos
