<h1>Themes: Getting Started</h1>
|
|
<p>The Semantic Web is a way of describing things in the world and
|
|
their relationships in a decentralized way. Resource Description
|
|
Framework (RDF) is the key technology which enables computers to
|
|
process some of the information humans take for granted when we
|
|
write on the web about (for example) people, places, time,
|
|
documents, and how these things relate to each other.</p>
|
|
<h2>Applications, specifications and help</h2>
|
|
<h3>What you can do with the Semantic web</h3>
|
|
<p>Here are <a href=
|
|
"http://esw.w3.org/mt/esw/archives/cat_applications_and_demos.html">
|
|
some Semantic Web applications</a> to show some of the ways that
|
|
people are using Semantic Web technologies, including photo
|
|
description applications, authoring and browsing tools. SWAD-Europe
|
|
has produced four Semantic Web demonstrators: <a href=
|
|
"http://www.w3.org/2001/sw/Europe/showcase/sem-blog.html">Semantic
|
|
Blogging</a>, <a href=
|
|
"http://www.w3.org/2001/sw/Europe/showcase/sem-portal.html">Semantic
|
|
Portal (the SWED environmental directory)</a>, <a href=
|
|
"http://www.w3.org/2001/sw/Europe/showcase/sem-thes.html">a
|
|
thesaurus browser</a> and <a href=
|
|
"http://www.w3.org/2001/sw/Europe/showcase/sem-large.html">a
|
|
large-scale demonstrator</a>. In addition the project produced a
|
|
<a href=
|
|
"http://www.w3.org/2001/sw/Europe/reports/report_semweb_access_tools/">
|
|
javascript image annotation demonstrator</a>.</p>
|
|
<h3>Specifications and working groups</h3>
|
|
<p>Semantic Web specifications are available from the <a href=
|
|
"http://www.w3.org/2001/sw/">W3C's Semantic Web page</a>.
|
|
SWAD-Europe has been very active in W3C specification development.
|
|
Dan Brickley co-chaired the <a href="http://www.w3.org/2001/sw/RDFCore/">RDF
|
|
Core working Group</a>, which clarified
|
|
the RDF specifications between 2001 and 2004; while other members
|
|
worked on testcases and other documents within this group. Project
|
|
members have also been active in the <a
|
|
href="http://www.w3.org/2001/sw/DataAccess/">W3C Data Access
|
|
Working Group</a>, which has been deciding on a query language for RDF;
|
|
others participate in the <a
|
|
href="http://www.w3.org/2001/sw/BestPractices/">W3C
|
|
Semantic Web Best Practices Working
|
|
Group</a>, which is working to write down some of the formal and informal
|
|
knowledge about the creation and management of vocabularies,
|
|
modelling techniques, and certain vocabularies themselves (e.g.
|
|
Wordnet, thesauri).</p>
|
|
<h3>Getting help</h3>
|
|
<p>There are many informal groups working in this area. The main
|
|
one is the <a href="http://www.w3.org/2001/sw/interest/">Semantic
|
|
Web interest Group</a>, a good place to ask questions, whether via
|
|
the mailing list or the IRC channel. More information can be found
|
|
on the <a href="http://esw.w3.org/topic/">ESW wiki</a>, a community driven
|
|
information source.
|
|
<a href="http://planet.rdfhack.com/">Planet RDF</a> is an informal place to
|
|
keep track of webloggers in this
|
|
area. SWAD-Europe team members are active in all these communities, and
|
|
have sought to maintain an online presence in these areas in order
|
|
to help answer questions from users and developers of the
|
|
technologies. There are active communities in the specific areas of
|
|
image annotation, calendaring, thesauri, geographical information,
|
|
and information about people. There is also an active
|
|
Spanish-speaking developer community. SWAD-Europe has a
|
|
<a href="http://www.w3.org/2001/sw/Europe/reports/community/">specific
|
|
page</a> about its
|
|
role in community development.</p> <h2>Vocabularies and ontologies</h2>
|
|
<p>Semantic Web vocabularies and ontologies are ways of describing
|
|
the world and can be very broad (e.g. Wordnet, a dictionary) or
|
|
very narrow (for example the Geo vocabulary, which only has three
|
|
properties and one class). Good places to look for information on
|
|
existing vocabularies are Schemaweb and Ontaria, and the Semantic
|
|
Web Best Practices working group is working on notes about
|
|
modelling ontologies and about maintaining vocabularies.
|
|
SWAD-Europe work in this area has included significant work
|
|
creating a thesaurus vocabulary and community, work towards a
|
|
calendaring RDF vocabulary, and work on image description.</p>
|
|
<h2>Tools</h2>
|
|
<p>Many tools for creating, parsing and storing Semantic Web data
|
|
are now available in multiple languages. A good starting point is
|
|
<a href=
|
|
"http://www.ilrt.bris.ac.uk/discovery/rdf/resources/#sec-tools">Dave
|
|
Beckett's RDF resource guide, tools section</a>. SWAD-Europe has a
|
|
<a href="http://www.w3.org/2001/sw/Europe/reports/tools/">tools
|
|
page</a> detailing work on tools support within the project,
|
|
including work test cases for RDF query languages which input into
|
|
the Data Access W3C Working Group and surveys of RDF APis and Tools
|
|
for scalable storage of RDF data. SWAD-Europe also supported work
|
|
on the Redland RDF application framework.</p>
|
|
<p>Developers were the main focus of SWAD-Europe's outreach work,
|
|
and details of the ten developer workshops held as part of the
|
|
project can be found on the <a href=
|
|
"http://www.w3.org/2001/sw/Europe/reports/community/">community
|
|
building</a> page. SWAD-Europe held workshops on Calendaring, image
|
|
annotation, Dublin Core, and FOAF and Social Software among other
|
|
topics.</p>
