Linked Data - Design Issues

Linked Data - Design Issues
Up to Design Issues The Semantic Web isn't just about putting data on the web. It is about making links, so that a person or machine can explore the web of data. With linked data, when you have some of it, you can find other, related, data. Like the web of hypertext, the web of data is constructed with documents on the web. However, unlike the web of hypertext, where links are relationships anchors in hypertext documents written in HTML, for data they links between arbitrary things described by RDF,. Use URIs as names for things Use HTTP URIs so that people can look up those names. Simple. The four rules I'll refer to the steps above as rules, but they are expectations of behavior. The first rule, to identify things with URIs, is pretty much understood by most people doing semantic web technology. The second rule, to use HTTP URIs, is also widely understood. The basic format here for RDF/XML, with its popular alternative serialization N3 (or Turtle). Basic web look-up or in RDF/XML

What Is Digital Humanities and What’s it Doing in the Library? tl;dr – Libraries and digital humanities have the same goals. Stop asking if the library has a role, or what it is, and start getting involved in digital projects that are already happening. Advocate for new expanded roles and responsibilities to be able to do this. Become producers/creators in collaboration with scholars rather than servants to them.

LinkedData - ESW Wiki LinkedData is to spreadsheets and databases what the Web of hypertext documents is to word processor files. Use URIs as names for things Use HTTP URIs so that people can look up those names. When someone looks up a URI, provide useful information. Include links to other URIs. so that they can discover more things groupage cargo service. Linked Data Presentations: Tim Berners-Lee Biography A graduate of Oxford University, Tim Berners-Lee invented the World Wide Web, an internet-based hypermedia initiative for global information sharing while at CERN, the European Particle Physics Laboratory, in 1989. He wrote the first web client and server in 1990. His specifications of URIs, HTTP and HTML were refined as Web technology spread.

Linked Data Patterns SweoIG/TaskForces/CommunityProjects/LinkingOpenData - ESW Wiki News 2014-12-03: The 8th edition of the Linked Data on the Web workshop will take place at WWW2015 in Florence, Italy. The paper submission deadline for the workshop is 15 March, 2015. 2014-09-10: An updated version of the LOD Cloud diagram has been published. The new version contains 570 linked datasets which are connected by 2909 linksets. New statistics about the adoption of the Linked Data best practices are found in an updated version of the State of the LOD Cloud document. 2014-04-26: The 7th edition of the Linked Data on the Web workshop took place at WWW2014 in Seoul, Korea. Dereferenceable Uniform Resource Identifier A dereferenceable Uniform Resource Identifier or dereferenceable URI is a resource retrieval mechanism that uses any of the internet protocols (e.g. HTTP) to obtain a copy or representation of the resource it identifies. In the context of traditional HTML web pages, this is the normal and obvious way of working: A URI refers to the page, and when requested the web server returns a copy of it. In other non-dereferenceable contexts, such as XML Schema, the namespace identifier is still a URI, but this is simply an identifier (i.e. a namespace name). There is no intention that this can or should be dereferenced. There is even a separate attribute, schemaLocation, which may contain a dereferenceable URI that does point to a copy of the schema document.

Linked Data: Evolving the Web into a Global Data Space Open Data An introductory overview of Linked Open Data in the context of cultural institutions. Clear labeling of the licensing terms is a key component of Open data, and icons like the one pictured here are being used for that purpose. Overview[edit] The concept of open data is not new; but a formalized definition is relatively new—the primary such formalization being that in the Open Definition which can be summarized in the statement that "A piece of data is open if anyone is free to use, reuse, and redistribute it — subject only, at most, to the requirement to attribute and/or share-alike. Toward a Basic Profile for Linked Data Update In March 2012, IBM and its partners submitted the Linked Data Basic Profile specification to W3C. Motivation There is interest in using Linked Data technologies for more than one purpose.

How to publish Linked Data on the Web This document provides a tutorial on how to publish Linked Data on the Web. After a general overview of the concept of Linked Data, we describe several practical recipes for publishing information as Linked Data on the Web. This tutorial has been superseeded by the book Linked Data: Evolving the Web into a Global Data Space written by Tom Heath and Christian Bizer. Extensible use of RDF in a Business Context Kerstin Forsberg, Viktoria Institute and Adera, O Hamngatan 41-43, S-411 10 Gothenburg Sweden, kerstin.forsberg@aderagroup.com Lars Dannstedt, Volvo Information Technology, Web Program Center, S-405 08, Gothenburg Sweden, it1.larsd@memo.volvo.se Abstract The next generation of intranets should facilitate the structuring of information as well as the organising of communication in networking organisations. For many organisations, one step in that direction is to structure information by adding metadata. We have encountered problems when applying Dublin Core, a metadata element set developed for discovery of existing information resources on the public Internet, on an extensive intranet.

Tools - Semantic Web Standards Overview This Wiki contains a collection of tool references that can help in developing Semantic Web applications. These include complete development environments, editors, libraries or modules for various programming languages, specialized browsers, etc. The goal is to list such tools and not Semantic Web applications in general (the interested reader may consider looking at the W3C SW Use Case Collection for those.)

IsaViz Overview News IsaViz and Java 1.6 (2007-10-21) IsaViz 2.x is not compatible with Java 1.6 or later. It is recommended to download IsaViz 3.0 which does work with any version of Java. An alpha release is available (see Download section), which should be as stable as IsaViz 2.1 except for the new, still under development, Fresnel and FSL features. IsaViz and GraphViz (2007-05-23)

1. Use URIs as names for things 2. Use HTTP URIs so that people can look up those names. 3. When someone looks up a URI, provide useful information, using the standards (RDF, SPARQL) 4. Include links to other URIs. so that they can discover more things. by nicolas Jul 4
