RDF 1.1 Primer Abstract This primer is designed to provide the reader with the basic knowledge required to effectively use RDF. It introduces the basic concepts of RDF and shows concrete examples of the use of RDF. Secs. 3-5 can be used as a minimalist introduction into the key elements of RDF. Changes between RDF 1.1 and RDF 1.0 (2004 version) are summarized in a separate document: "What's New in RDF 1.1" [RDF11-NEW]. Status of This Document
Language subtag lookup app BCP 47 language tags are built from subtags in the IANA Subtag Registry. This tool helps you find or look up subtags and check for errors in language tags. Read Choosing a Language Tag for step-by-step guidelines on creating language tags. This tool also provides information to guide your choices. 1 Raw data. Language tags in HTML and XML Overview Terminology In this article we refer to the value of a language attribute such as fr-CA as a language tag. The fr and CA parts are referred to as subtags when described as parts of a tag. When described as members of an ISO list of languages or countries, fr and CA are referred to as codes.
RDFa Distiller and Parser This distiller corresponds to the RDFa 1.0 specification. In 2012, W3C has published an updated version of that specification, called RDFa Core 1.1. A new distiller, processing RDFa 1.1 content, has been implemented which suprecedes this one. Note that the new distiller can also process RDFa 1.0 content (there are some minor incompatibilities) if the XHTML+RDFa file uses the right (RDFa 1.0) DTD and/or the @version attribute.
Hash vs. Slash: What Is Identified? from Sean B. Palmer on 2001-11-28 (firstname.lastname@example.org from November 2001) To hash or to slash... here are some things to consider. This is also me doing my bit for rdfms-fragments . Abstract: The question is whether or not "namespaces" on the Semantic Web should end with a hash "#", or a slash "/" (or even a question mark "?"). For example, the RDF Schema terms are all in the "namespace":- wheras the Dublin Core terms are in:- The difference? Terms with the former will necessarily be URI-references, that is, a URI with a FragmentID on the end, whereas terms with the latter will most likely be URIs. TimBL's view is, apparently, that of the hashist.
Google Developers Add markup to your product pages so Google can provide detailed product information in rich Search results — including Google Images. Users can see price, availability, and review ratings right on Search results. Using markup to enable rich product results lets you attract potential buyers while they are searching for items to buy on Google or images that include products you sell. 15 amazing tools for online collaboration Individuals in design teams don't always work together in the same office. You may be positioned in distributed groups, or working from home, and clients can come from all over the world. This is where collaboration tools come in – they make it easier and faster for designers to get feedback and approve artwork in a professional manner, and they come in all sort of forms, from free Android apps to Chrome extensions. Here we gather together some of the best available online tools to allow designers to collaborate together in real time. Some are created specifically for designers, some serve as a concept crafting whiteboard, and we've also included some more full-on project management tools for when you need to take your collaborative project to the next level.
Haystack Blog » A Quick Tutorial on the Turtle RDF Serialization This post was going to be an email to a project mate in my database class, but I found myself wanting to markup the text in HTML so I figured I’d put it here. Unlike web specifications like HTML, which have only one representation on paper/disk, RDF is just an abstract model — it doesn’t matter how you represent it as long as you stay true to its abstract properties. So one of the first things people ask when it comes to RDF is, “Ok, so how to I write it?” If you Google the web for this answer, you will probably come up with RDF/XML as your answer, which is the “official” representation. Unfortunately it is also a pretty painful and hard-to-read one, too.

Go to OData Version 4.0 Digitised Manuscripts Almost 900 Greek manuscripts and some of the most important papyri, ranging in date from the first to the 18th centuries, are now included in the Digitised Manuscripts site. The first two phases of the Greek Manuscripts Digitisation Project were generously funded by the Stavros Niarchos Foundation and the third phase was funded by the Stavros Niarchos Foundation, the A. G. Leventis Foundation, Sam Fogg, the Sylvia Ioannou Foundation, the Thriplow Charitable Trust, and the Friends of the British Library. A guide to the Greek Manuscripts collections, including articles, videos and collection highlights, is available here. Over fifty Thai manuscripts and the Chakrabongse Archive of Royal Letters have been digitised with the generous support of the Royal Thai Government, in celebration of the occasion of the eightieth birthday anniversary of His Majesty King Bhumibol Adulyadej of Thailand on 5 December 2007.
Tutorial: Jena Semantic Web Framework Today I was poking around the Jena RDF Framework, mostly to figure out how one would use an OWL reasoner there. The Data My test ontology is fairly simple: @prefix xsd:< .@prefix:< . NCBI RDF URI Standards – Linked Data for Professional Education Topic: Publishing RDF; Competency: Determines whether to use hash (#) or slash (/). This document describes standards for NCBI-minted persistent URIs that identify RDF resources. The goals of this document include: Provide guidance to help projects get started publishing data on the Semantic Web; Provide standards and recommendations for the forms that the published RDF URIs should take; Provide distributed authority and control, that allows for groups/projects to mint their own identifiers, by providing namespaces; Specify a centralized system for handling HTTP requests to RDF URIs, in accordance with current best practices (e.g. HTTP 303 redirects) URL: RDF, HTTP URIsAuthor: Maloney, ChrisPublisher: National Center for Biotechnology InformationLanguage: required: P10MInteractivity type: expositive
8 Regular Expressions You Should Know Regular expressions are a language of their own. When you learn a new programming language, they're this little sub-language that makes no sense at first glance. Many times you have to read another tutorial, article, or book just to understand the "simple" pattern described. Today, we'll review eight regular expressions that you should know for your next coding project. Before we start, you might want to check out some of the regex apps on Envato Market, such as:
