API to erase/update Triples in TripleStore

[Shankar Nair]

Hi,

I would like know if the library exposes an API to erase or modify already existing triples in the tripleStore.

To be more specific, I have a DatatypeProperty of type xsd_string for an instance that I need to modify. I am able to insert it but now I need to update that string literal. So either a eraseOld-insertNew or modifyOld API is what I am looking for.

Also, is there a way to flush the changes back to the OWL file. Something like a save_file() API?

Any help is appreciated.

Cheers,
Shankar

Hello Shankar,

The method to erase triples from the triple store was not exposed. It IS now in the head of the master branch:

void Triple_store::erase(Triple const&);

Thank you for catching this!

Existing nodes and triples cannot be modified. You can create a new literal node and use it in your triples.

There is currently no method to write triples to a file. This will be implemented in the future.

Best

This library has been really useful in my project.
Thank you for the efforts!
