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 ...

Schema.org 6.0

Schema.org version 6.0 has been released. See the release notes for full details. Versions 5.0 , and 4.0 also added many improvements and additions, even if we forgot to blog about them. As always, the release notes have details (and links to even more details). We are now aiming to release updated schemas on an approximately monthly basis (with longer gaps around vacation periods). Typically, new terms are first added to our "Pending" area to give time for the definitions to benefit from implementation experience before they are added to the "core" of Schema.org. As always, many thanks to everyone ...

Help! Digital Object Identifiers: Usability reduced if given at the bottom of the page

The (for J. Cheminform. ) new SpringerNature article template has the Digital Object Identifier (DOI) at the bottom of the article page. So, every time I want to use the DOI I have to scroll all the way down to the page. That could be find for abstracts, but totally unusable for Open Access articles. So, after our J. Cheminform. editors telcon this Monday, I started a Twitter poll : Where I want the DOI? At the top, with the other metadata: Recent article in the Journal of Cheminformatics. If you agree, please vote . With enough votes, we can ...

Common Tag semantic tagging format released today

The Common Tag format for semantic tagging has been finally released today after almost a year of intense work on it by a group of Web companies active in the semantic technologies area, among them Yahoo. It's been great fun working on this and I'm proud to have been involved: while there have been vocabularies before for representing tags in RDF, this effort is different in at least two respects. First, a significant effort of time has been spent on making sure the specification meets the needs of all partners involved. The support of these companies for the specification will ...

Simplified RDF

I propose that we designate a certain subset of the RDF model as "Simplified RDF" and standardize a method of encoding full RDF in Simplified RDF. The subset I have in mind is exactly the subset used by Facebook's Open Graph Protocol (OGP) , and my proposed encoding technique is relatively straightforward. I've been mulling over this approach for a few months, and I'm fairly confident it will work, but I don't claim to have all the details perfect yet. Comments and discussion are quite welcome, on this posting or on the semantic-web@w3.org mailing list. This discussion, I'm afraid, is ...

Lets talk about plugs

This is a summary of a short talk I gave internally at the ODI to help illustrate some of the important aspects of data standards for non-technical folk. I thought I'd write it up here too, in case its useful for anyone else. Let me know what you think. We benefit from standards in every aspect of our daily lives. But because we take them for granted, we don't tend to think about them very much. At the ODI we're frequently talking about standards for data which, if you don't have a technical background, might be even harder to wrap ...

Some of my (very) preliminary opinions on Google Wave

I was interviewed by Marie Boran from Silicon Republic recently for an interesting article she was writing entitled " Will Google Wave topple the e-mail status quo and change the way we work? ". I thought that maybe my longer answers may be of interest and am pasting them below. Disclaimer: My knowledge of Google Wave is second hand through various videos and demonstrations I've seen… Also, my answers were written pretty quickly! As someone who is both behind Ireland's biggest online community boards.ie and a researcher at DERI on the Semantic Web , are you excited about Google Wave? ...

Open government and Linked Data; now it's time to draft…

For the past few months, there have been a variety of calls for feedback and suggestions on how the US Government can move towards becoming more open and transparent, especially in terms of their dealings with citizens and also for disseminating information about their recent financial stimulus package. As part of this, the National Dialogue forum was set up to solicit solutions for ways of monitoring the "expenditure and use of recovery funds". Tim Berners-Lee wrote a proposal on how linked open data could provide semantically-rich, linkable and reusable data from Recovery.gov . I also blogged about this recently , ...

Idea for Linked Open Data from the US recovery effort

Tim Berners-Lee recently posted an important request for the provision of Linked Open Data from the US recovery effort website Recovery.gov . The National Dialogue website (set up to solicit ideas for data collection , storage, warehousing, analysis and visualisation; website design ; waste, fraud and abuse detection; and other solutions for transparency and accountability) says that for Recovery.gov to be a useful portal for citizens, it "requires finding innovative ways to integrate, track, and display data from thousands of federal, state, and local entities". If you support the idea of Linked Open Data from Recovery.gov, you can have a ...
