A little story about OData and Linked Data … Others already gave some high-level overview about OData and Linked Data, but I was interested in two concrete questions: how to utilise OData in the Linked Data Web and how to turn Linked Data into OData. As already mentioned, I consider Atom, which forms one core … Continue reading
Jan Algermissen recently compiled a very useful Classification of HTTP-based APIs. This, together with Mike Amundsen‘s interesting review of Hypermedia Types made me think about data and the Web. One important aspect of data is “on the Web vs. in the Web” as Rick Jelliffe already highlighted in 2002: To explain my POV, let me … Continue reading
This post has been triggered by a Twitter thread, where I replied to @olyerickson that I think https://subj3ct.com is a good thing to have. Then, @hvdsomp noted (rightly!) that registries don’t scale (in reference to a conversation we had earlier on). Big confusion, right? Michael says one thing and then the opposite on the very … Continue reading
I stumbled over a tweet from Mike Amundsen where he essentially asked people to name some more “widely-used hypermedia-types” beside (X)HTML and Atom. Turns our Mike collected the findings and made it available at http://amundsen.com/hypermedia/. Cool. Thanks! Couple of days later I read Linking data in XML and HATEOAS where Wilhelm contemplates about Linked Data … Continue reading
Less than a year ago I asked W3C’s Technical Architecture Group (TAG) essentially if … the [image] representation derived via [content negotiation from a generic resource] is equivalent to the RDF [served from it] I asked for a “a note, a specification, etc. that normatively defines what equivalency really is”. So, after some back and … Continue reading
One of the often overlooked, IMO yet important features of RESTful applications is “hypermedia as the engine of application state” (or HATEOS as RESTafarians prefer it 😉 – Roy commented on this issue a while ago: When representations are provided in hypertext form with typed relations (using microformats of HTML, RDF in N3 or XML, … Continue reading
Reading RESTful Web Services by Leonard Richardson and Sam Ruby, it suddenly stroke my like thunder: yes indeed, it’s very often the case with technologies that they are (often unknowingly) abused in obscure ways, which then is often perceived by the community as good or best practice. So much generic introduction for explaining the title … Continue reading
My colleague Juergen Umbrich and I had a reading group on POWDER and related technologies yesterday here at DERI. There were some interesting questions and discussion around that, esp. regarding the involved costs for implementing such mechanisms, the use cases and the progress in this area. The resource and metadata discovery domain seems all in … Continue reading
Just stumbled upon Data Discovery (Spotlight), a research report available for free (downside: you need to register to download it): Data discovery or, more precisely, data relationship discovery, is of fundamental importance to a wide range of functions ranging from business intelligence through master data management to data governance and data archival. Nevertheless, it has … Continue reading
