but if I were to build something production grade that needs good performance I would use Jena or RDF4J
I think the best hope is to find more commercial applications for RDF
The more commercial use the more funding and more contributions
But if universities were better actors in the ecosystem it would help, if they instead direct resources to maintaining existing stuff instead of making yet another research project that will be abandoned it would be very beneificial
I am going to submit a fix for tox this weekend, and then also submit changes to add mypy to CI pipeline (and eventually to tox) - hope it is well received. I will also try and make CONTRIBUTING.md similar to this: https://github.com/pallets/click/blob/main/CONTRIBUTING.rst
better to have that in Repo IMO
@aucampia: If you are planning to invest more time in performing big changes or something alike, we can also try to schedule a call with @ashleysommer and Nicholas to so how we can best organize this.
I am open to it, I want to help where I can but I don't really have dedicated time for it. For me it is easier to navigate the code base with type annotations. Besides this I am just looking at small issues to try and get a better understanding of the code base. I will look at the backlog for 6.0.0 where I can, some of it looks quite complicated, the RDF 1.1. test suite looks like a decent thing to try do and not that complicated, but I have not quite built up the courage for starting on that. Actual bug I will look at next is RDFLib/rdflib#1228
But I think that is the case, or have no reason to think it is not the case

If there are any PRs you want me to review I can have a look, I keep an eye out for small and easy ones where I have some knowledge about the implementation but the more complex ones I won't necessarily review unless someone makes an explicit request
bridge works well
Thanks for review BTW
Which matrix room did you bridge? Am I in the gitter room or in the native matrix room?
noting is bridged other than through automatic bridges
Does anyone have code snippets/patterns to share on how to properly deal with reification in rdflib? I'm planning to use python + rdflib to create a graph from a few sources, and I am planning to use reification for provenance (learned fact X from source Y) as well as for temporality (X worked at Y since Z). I found it odd that there was nothing about that in the docs
If it is not RDF* then there is no specific language support
or library support
Well there is no specific RDF* support either
I will try make an example though on using RDF 1.1 recommendation for reification (i.e. rdf:Statement IIRC)

Thanks @aucampia! I am starting from scratch here, so if RDF* was available then I'd probably go with that since it's the next big standard, but just good old RDF 1.1 would be ok
import rdflib
from rdflib.namespace import RDF
lit2019 = rdflib.Literal('2019-01-01', datatype=rdflib.XSD.date)
lit2020 = rdflib.Literal('2020-01-01', datatype=rdflib.XSD.date)
bob = rdflib.URIRef("http://example.org/people/Bob")
google = rdflib.URIRef("http://example.org/companies/Google")
workedAt = rdflib.URIRef("http://example.org/stuff/0.1/workedAt")
startTime = rdflib.URIRef("http://example.org/stuff/0.1/startTime")
endTime = rdflib.URIRef("http://example.org/stuff/0.1/endTime")
g = rdflib.Graph()
position = (bob, workedAt, google)
reified_position = (position, RDF.type, RDF.Statement)
g.add(position)
g.add(reified_position)
g.add((reified_position, startTime, lit2019))I tried running this but can't add that second triple, I guess I'd have to make it a BNode?
hope that helps
will maybe share it on stackoverflow also
though not sure it is extremely idomatic
Always glad to have more people using it :)
Another great place to ask for help in general is https://gitter.im/linkeddata/chat - but that is just general semantic web and not rdflib specific
