Cloud Cipher Capabilities

… or, the lack of it. A recent discussion at a customer made me having a closer look around support for encryption in the context of XaaS cloud service offerings as well as concerning Hadoop. In general, this can be broken down into over-the-wire (cf. SSL/ TLS ) and back-end encryption. While the former is widely used, the latter is rather seldom to find. Different reasons might exits why one wants to encrypt her data, ranging from preserving a competitive advantage to end-user privacy issues. No matter why someone wants to encrypt the data, the question is do systems support ...

Microdata, semantic markup for both RDFers and non-RDFers

There's been a whole lot of discussion around Microdata , a new approach for embedding machine-readable information into forthcoming HTML5. What I find most attractive about Microdata is the fact that it was designed by HTMLers, not RDFers. It's refreshingly pragmatic, free of other RDF spec legacy, but still capable of expressing most of RDF. Unfortunately, RDFa lobbyists on the HTML WG mailing list forced the spec out of HTML5 core for the time being. This manoeuver was understandable (a lot of energy went into RDFa, after all), but in my opinion very short-sighted. How many uphill battles did we ...

Linked Data Entity Extraction with Zemanta and OpenCalais

I had another look at the Named Entity Extraction APIs by Zemanta and OpenCalais for some product launch demos. My first test from last year concentrated more on the Zemanta API. This time I had a closer look at both services, trying to identify the "better one" for "BlogDB", a semi-automatic blog semantifier. My main need is a service that receives a cleaned-up plain text version of a blog post and returns normalized tags and reusable entity identifiers. So, the findings in this post are rather technical and just related to the BlogDB requirements. I ignored features which could well ...

Could having two RDF-in-HTMLs actually be handy?

Apart from grumpy rants about the complexity of W3C's RDF specs and semantic richtext editing excitement , I haven't blogged or tweeted a lot recently. That's partly because there finally is increased demand for the stuff I'm doing at semsol (agency-style SemWeb development), but also because I've been working hard on getting my tools in a state where they feel more like typical Web frameworks and apps. Talis ' Fanhu.bz is an example where (I think) we found a good balance between powerful RDF capabilities (data re-purposing, remote models, data augmentation, a crazy army of inference bots) and a non-technical ...

Moving forward back to Self-Employment

My time at Talis Systems officially ended last week. I joined the team during painful times , but I'm glad (and proud) to have been a Talisian at least for one year. I have had a few freelance gigs with Talis before, but being part of the team was a whole different thing. And I could frequently travel to the UK, immprooff my inklish, and discover the nice city of Birmingham. There's a reason why they have that G in GB. Work-wise, I probably learned more in the last 12 months than during the previous 5 years combined - hat ...

Dynamic Semantic Publishing for any Blog (Part 1)

"Dynamic Semantic Publishing" is a new technical term which was introduced by the BBC's online team a few weeks ago. It describes the idea of utilizing Linked Data technology to automate the aggregation and publication of interrelated content objects. The BBC's World Cup website was the first large mainstream website to use this method. It provides hundreds of automatically generated, topically composed pages for individual football entities (players, teams, groups) and related articles. Now, the added value of such linked "entity hubs" would clearly be very interesting for other websites and blogs as well. They are multi-dimensional entry points to ...

I'm joining Talis!

I received a number of very interesting job offers when I began searching for something new last month, but there was one company that stood out, and that is Talis . Not only do I know many people there already, I also find Talis' new strategic focus and products very promising. In addition, they know and use some of my tools already, and I've successfully worked on Talis projects with Leigh and Keith before. The job interview almost felt like coming home (and the new office is just great). So I'm very happy to say that I'm going to become ...

Schema.org 3.5: Simpler extension model, projects, grants and funding schemas, and new terms for describing educational and occupational credentials

Schema.org version 3.5 has been released. This release moves a number of terms from the experimental " Pending " area into the Schema.org core. It also simplifies and clarifies the Schema.org extension model, reducing our emphasis on using named subdomains for topical groups of schemas. New terms introduced in Pending area include improvements for describing projects, grants and funding agencies; for describing open-ended date ranges (e.g. datasets); and a substantial vocabulary for Educational and Occupational Credentials . Many thanks to all who contributed!

An i2c heat sensor with a Raspberry Pi camera

I had a bit of a struggle with this so thought it was worth documenting. The problem is this - the i2c bus on the Raspberry Pi is used by the official camera to initialise it. So if you want to use an i2c device at the same time as the camera, the device will stop working after a few minutes. Here's more on this problem . I really wanted to use this heatsensor with mynaturewatch to see if we could exclude some of the problem with false positives (trees waving in the breeze and similar). I've not got it ...

Thinking about the governance of data

I find "governance" to be a tricky word. Particularly when we're talking about the governance of data. For example, I've experienced conversations with people from a public policy background and people with a background in data management, where its clear that there are different perspectives. From a policy perspective, governance of data could be described as the work that governments do to enforce, encourage or enable an environment where data works for everyone . Which is slightly different to the work that organisations do in order to ensure that data is treated as an asset , which is how I ...

Comparing Research Journals Quality #1: FAIRness of journal articles

What a traditional research article looks like. Nice layout, hard to reuse the knowledge from. Image: CC BY-SA 4.0 . After Plan S was proposed, there finally was a community-wide discussion on the future of publishing. Not everyone is clearly speaking out if they want open access or not, but there's a start for more. Plan S aims to reform the current model. (Interestingly, the argument that not a lot of journals are currently "compliant" is sort of the point of the Plan.) One thing it does not want to reform, is the quality of the good journals (at least, ...
