One of the more opaque aspects of learning about linked data can be understanding and using SPARQL to query RDF triple stores. In a recent post to the LODLAM Google group (which originated on the CODE4LIB list) Arwen Hutt (Geisel Library, University of California, San Diego) asked a question about any SPARQL workshops that might be available. He received references to a number of good resources that I thought I’d highlight for anyone interested in learning to SPARQL.

Occasionally I like to crowd-source an answer to a question here at Slaw as I appreciate the insight and experience that Slaw-yers bring to the table. Today is one of those times when I have such a question that I have been turning over in my mind. Before I pose my question I want to state that I ask it in all earnestness; I also want to preface my question by stating that I am a huge fan and user of Twitter, it is currently one of my top current awareness tools. That being said one thing bothers me a . . . [more]
Years before Edward Snowden obliterated digital innocence, showed us what the “Five Eyes” are really up to, and pulled stakes for the unlikely safe harbour of Moscow’s airport transit zone, Viktor Mayer-Schönberger released his 2009 book Delete: The Virtue of Forgetting in the Digital Age. In it he urged caution for the “Digital Panopticon”, and warned against the growing trend towards mass surveillance. The Internet, as we now know, never forgets. He made the case for why it should.
Throughout human history, forgetting has been the norm and remembering the exception. Technology, as Mayer-Schönberger, a . . . [more]
Eric Franzon, over on semanticweb.com, has a nice post about a series of videos on semantic web and linked data technologies.
The series is called Build a Small Knowledge Graph and there are three videos:
- Creating and Processing Linked Data
Jarek Wilkiewicz introduces the reference architecture for support of Schema.org Actions in the context of a specific use case (a music store). The video then focuses on exposing entities using Schema.org markup with JSON-LD.
- Managing Graph Data With Cayley
Barak Michener introduces graph processing using Cayley, an open source graph database written in Go. Cayley is fast,
On the heels of the European Court of Justice’s decision, discussed on Slaw here and here, to require Google to suppress links to particular web sites that had ‘irrelevant and outdated’ personal information about a complainant, and US courts’ refusal to do the same, the British Columbia Supreme Court has now gone a step further: it has ordered Google to ensure that searches for particular topics or a particular company do not find the company defendant in the action before it.
The principals of the defendant company were accused of stealing trade secrets of the plaintiff and of . . . [more]
Sub Nomine the Sub Nom rule is one of those delightful pieces of legal Latin that I quite enjoy. I like that two words in Latin can effectively sum up a legal thought that takes at least a sentence or two in English. Sub Nom is Latin for “under the name of” or in everyday parlance, “also known as”. The most recent case from the SCC that has caused a stir in legal circles, R v Spencer, 2014 SCC 43 in which the SCC rules that police organizations cannot simply ask ISPs for the IP information of subscribers and . . .

The Canadian Association of Law Libraries List (CALL-L) is an e-mail discussion list fostering an interest in and discussion on law librarianship in Canada. A message went out today from CALL-L list owner/manager Susan Jones at the University of New Brunswick to all subscribers asking us to “opt in” to being on the list.
This measure is being taken to comply with Canada’s new anti-spam legislation coming into force on July 1st. While the list itself is not a commercial vehicle, some of the messages posted may be interpreted as such. From the message to subscribers:

The Supreme Court of Canada has released its judgment in the Spencer case. It held that the police had no legal right to ask an ISP for subscriber information, as that would violate the subscriber’s reasonable expectation of privacy. The type of information that could be gleaned from the information went beyond the mere name and address into browsing practices, i.e. sensitive information in which the subscriber might reasonably expect anonymity.
The section of PIPEDA that allows custodians of data to disclose the data to law enforcement officials without telling the data subject, did not apply where the search . . . [more]
From the start, I’ve wondered how we will navigate in a linked data environment. How will we explore an information space where every data element is linked to every other data element? How will we keep track of where we are and where we’ve been? We won’t have physical cues anymore and the navigation systems we are familiar with grew out of our interaction with those physical cues (e.g. think card catalogue to online catalogue).
Google’s new Video Quality Report tool allows you to compare video streaming capabilities between local ISPs.
By viewing this report, either at home or at work, you are able to see when the prime video streaming periods are. You can also see how your current streaming performance compares against other local ISPs competing for your business.
Here’s a screen capture from my report:

A Spanish citizen has compelled Google to delete links to online newspaper articles that described the person’s debt problems in the 1990s. The European Court of Justice held that the information was ‘no longer relevant’ and it thus violated the man’s privacy for it to be available through an easy search. (A Spanish court had earlier refused to require the newspaper sites to take down the information, which was perfectly true.)
So: does this ruling make any sense at all, to impose the obligations of a ‘data controller’ on a search engine?
How can the search provider know for sure . . . [more]
I am an avid reader of the website Lifehacker. Every day, there are new posts on an incredible range of topics with the single goal of making life easier. Yesterday, for example, there were hacks on communicating with seniors, peeling hardboiled eggs, getting roadside assistance for your bicycle and applying the GTD philosophy in dealing with your emails.
Lifehacker absolutely lives up to its motto:
Tips, tricks, and downloads for getting things done.
I’ve noticed that Lifehacker has a way of pinpointing issues in my daily life that I’ve not yet identified as issues, and in many cases, . . . [more]
