Yesterday I released an early version of sparql-doc a SPARQL documentation generator. I've got plans for improving the functionality of the tool, but I wanted to briefly document how to use github and sparql-doc to publish SPARQL queries and their documentation. Create a github project for the queries First, create a new github project to … Continue reading Publishing SPARQL queries and documentation using github
Developers often struggle with SPARQL queries. There aren't always enough good examples to play with when learning the language or when trying to get to grips with a new dataset. Data publishers often overlook the need to publish examples or, if they do, rarely include much descriptive documentation. I've also been involved with projects that … Continue reading sparql-doc
The Land Registry have today announced the publication of their Open Data -- including both Price Paid information and Transactions as Linked Data. This is great to see, as it means that there is another UK public body making a commitment to Linked Data publishing. I've taken some time to begin exploring the data. This … Continue reading A Brief Review of the Land Registry Linked Data
Mark Nottingham has posted a nice status report on the ongoing effort to revise HTTP 1.1 and specify HTTP 2.0. In the post Mark highlights a list of changes from RFC2616. This ought to be required reading for anyone doing web application development, particularly if you're building APIs. I thought it might be useful to skim … Continue reading HTTP 1.1 Changes Relevant to Linked Data
As I explained in that announcement that I'm leaving Talis, I'm going to be exploring freelance consulting opportunities.While I'm not limiting that to Linked Data work, its an area in which I have a lot invested and which there is still lots of activity. Perhaps not enough to support Talis Systems, but there certainly seems … Continue reading UK & EU Linked Data Consultant Network?
Having reviewed a number of Linked Data papers and projects I've noticed a recurring argument which goes something like this: "there are billions of triples available as Linked Data but the number of links, either within or between datasets, is still a small fraction of that total number. This is bad, and hence here is … Continue reading Four Links Good, Two Links Bad?
Everyone loves to hate RDF/XML. Indeed many have argued that RDF/XML is responsible for holding back semantic web adoption. I'm not sure that I fully agree with that (there's a lot of other issues to consider) but its certainly awkward to work with if you're trying to integrate both RDF and XML tools into your … Continue reading Principled use of RDF/XML
Two years ago I wrote a short paper about "layering" data but for various reasons never got round to putting it online. The paper tried to capture some of my thinking at the time about the opportunities and approaches for publishing and aggregating data on the web. I've finally got around to uploading it and … Continue reading Layered Data: A Paper & Some Commentary
This post was originally published on the Kasabi product blog. On Monday I gave a talk at the SemTechBiz conference: "The RDF Report Card: Beyond the Triple Count". I've published the slides on Slideshare which I've embedded below, but I thought I'd also post some of my notes here. The RDF Report Card: Beyond the Triple Count … Continue reading Beyond the Triple Count
This post was originally published on the Kasabi product blog. The following is a version of the talk on Creating APIs over RDF I gave at SemTech 2011. I've pruned some of the technical details in favour of linking out to other sources and concentrated here on the core message I was trying to get across. Comments … Continue reading Giving RDF Datasets more Affordance
