Talis Kasabi

[This email reads like a two-pronged advert... apols for that...]

One of the things that I griped on about at length over the last 18 months was how difficult it was to find useful example Linked Data queries, that the cut'n'paste'make-minor-changes-to brigade (amongst which I count myself) could use to bootstrap usage the Linked Data stores.

A few days ago, I went to the Talis Kasabi Linked Data datamart preview day, and it's looking quite handy from a "view source" point of view.

Datastores reside somewhere on the Talis Platfrom, and Kasabi (in its developer preview version at least - sign up at kasabi.com) has layer on top that provides:

- SPARQL endpoint (with ability to create and share example queries)

- Google Refine reconciliation api

- Linked Data api

You can also create "stored SPARQL procedures", that is, parameterised SPARQL queries that can be exposed via a RESTful URI, drop in Linked Data PAI templates to define your own Linked Data API over a dataset.

At the moment you can't upload a dataset, but have to make do with what's there.

On the timeline (I think) are tools to share common ontologies across datasets, analytics on usage etc

PS if you're a publisher or consumer of data, please check out GetTheData.org, a data related Q&A site set up earlier this year following a conversation between myself and Rufus Pollock. The idea of GetTheData is that it provides a clearninghouse for questions around the publication, discovery, reuse, and cleansing of data. Technical questions, as well as questions relating to data semantics, and even policy, are encouraged. If you have a spare few minutes and can help out answering (or improving answers to) any of the questions on site, please do so... and if you ever have your own data related question, why not post a query before you start Googling?!;-) (self-answered questions are also allowed if you manage to answer your own question.)

If you're publishing your own data set, and want to discuss whether or not we might be able to work out something around hosting technical FAQs around your data, please get in touch:-) FWIW, there's an open email list for getTheData at getthedat...@lists.okfn.org

Yes, but FWIW you've been able to cut, paste, and share SPARQL queries since 2007. It really isn't appropriate to conclude (emphatically) that such solutions have never existed.

I even once tried to show you how a single SPARQL protocol URL would fill up a Google Spreadsheet using its own in-built functions. I never got as much as "it worked" or "failed" from you style response.

I've never produced a demo that wasn't ultimately about being able to leverage cut and paste via permalinks (at the very least) when it comes to sharing Linked Data. The entry point is the URL (the Data Source Address) no platform specificity bar underlying functionality that a given platform can deliver via its data management and access functionality.
