Thanks for your reply, Nikos. That certainly sounds interesting. I'd like to know more about the platform, although I won't be making it to the hackfest in Marseille this year. How does RG handle Linked Data relationships? Say I was entering in a place of publication and wanted to use dbpedia's entry for New York City. I would provide the URI but what happens after that? Do I add a local triple to describe that external resource using a schema supported by RG, or does it fetch the RDF document from the remote server and let me decide what to import or transform? If you can direct me to the appropriate demo, I'd love to look more at how your system handles Linked Data. I think I've gone as far as there is to go with RDF on its own, but curious how existing systems are handling the links to external resources.

There isn't any community yet. We do provide the platform with l-GPL license in our installation, which are listed on the platform's website and are located in Greece. So we do not allocate any resources in maintaining a public repo. If a community arises, we will switch our private repos to the public one and do there our commits. This is the reason why our github repo seems abandoned. We too have implemented BIBFRAME 2.0, among other standards. Primarily for proof of concept and for providing demo installations. Our purpose is to demonstrate the fact that different ontologies can be quite easily implemented on our platform. Which has configuration files for describing any ontology and the entry forms necessary to manage it. For all our demo instalations, we provide full access to anyone who might be interested. Having said that, I come to your question regarding the use or possible value of RG for the KOHA ecosystem. We feel that RG can offer 2 valuable functions: 1) a real-time backend that transforms MARC21 or UNIMARC collections into FRBR or BIBFRAME datasets (or any other semantic model) 2) and the ability to simultaneously manage/annotate/enrich the collection on both standards. So it can act as the necessary tool for adopting the new standards. Helping to keep the MARC expertise and tools and at the same time experiment with the new standards. And the same time it allows libraries to explore the possibility of having unified repositories for all their collections (bibliographic, archival, museum, musical, etc). The demos mentioned by Paul are showcasing the above. Thanx to David and Paul for their comments. Looking forward to meeting you in Koha hackfest in Marseille Regards, Nikos PS: I am not a member of the koha-devel list yet.

I'm skeptical of anything that claims to implement BIBFRAME for production, since BIBFRAME appears to still be an experimental work in progress (https://www.loc.gov/bibframe/faqs/#q09). That said, it does seem like folk like Ex Libris are trying to use BIBFRAME 2.0 in production (https://www.loc.gov/bibframe/implementation/register.html). I suppose every technology needs its early adopters. I can see why places like Oslo Public Library, the National Library of Sweden, and la Bibliothèque Nationale de France are using their own schemas though.

The ReasonableGraph Github only seems to have 1 contributor and a handful of commits. Mostly from 1 year ago and 15 days ago. I wonder what is missing? I haven't had time to deep dive the code yet. https://github.com/reasonablegraph

That said, I'm intrigued by anything that claims to use Linked Data. To date, I've mostly only seen systems that use RDF stored locally. That is, that only link internally and don't resolve external links. The most interesting example of Linked Data that I've actually found is with OCLC WorldCat: http://www.worldcat.org/title/good-omens-the-nice-and-accurate-prophecies-of.... If you open the "Linked Data" section, you can see that "New York" from the top of the webpage comes from this predicate and object: library:placeOfPublication <http://dbpedia.org/resource/New_York_City>. The interesting bit is if you go down to "Related Entities", you'll see 'schema:name "New York"'. I find that interesting because http://dbpedia.org/page/New_York_City doesn't have a predicate of schema:name. So, in theory, OCLC must be converting a triple from another vocabulary into Schema.org. Either that or they provide the link as the authoritative link and ! then just add their own local triple saying "New York". I suppose that's a possibility too. But it kind of defeats the purpose of machine readable Linked Data. But Linked Data is hard since you never know what you're going to get back from the other end.

At this point, what could Reasonable Graph offer for Koha?

Apologies if that sounds rude at all. I've just been thinking a lot about RDF and Linked Data for the last couple of years.

Hi koha-devel,

I had a hangout with Nikos (in cc:) , from Reasonablegraph. reasonablegraph is a platform (L-GPL) that is able to deal with MARC records, transform them into FRBR / Bibframe /linked data. They made some work with Koha (http://unioncatalog.reasonablegraph.org/?lang=en, click on "Search" top-left)

At the end of Nikos demo, I suggested him to come to the hackfest for a day or two, in order to present reasonablegraph to anyone interested, and talk about any possible collaboration between Koha community and reasonablegraph. He will probably come.

That's another very good reason to come to Marseille in March :D
