In response to the "Semantic Web Technology" application
classification scheme espoused by ReadWriteWeb
(RWW), emphasized in the post titled: Where are all the RDF-based Semantic Web
Apps?, here is my attempt to clarify and reintroduce what
OpenLink Software offers (today) in
relation to Semantic Web technology.
From the RWW Top-Down category, which I interpret as:
technologies that produce RDF from non RDF data sources. Our product
portfolio is comprised of the following; Virtuoso
Universal Server, OpenLink Data Spaces, OpenLink Ajax
Toolkit, and OpenLink Data Explorer (which includes
ubiquity commands).
Virtuoso Universal Server functionality summary:
- Generation of RDF Linked Data Views of SQL,
XML, and Web Services in
general
- Deployment of RDF Linked Data
- "On the Fly" generation of RDF Linked Data from Document Web
information resources (i.e. distillation of
entities from their containers e.g. Web pages) via Cartridges /
Drivers
-
SPARQL query language support
- SPARQL extensions that bring SPARQL closer to SQL e.g
Aggregates, Update, Insert, Delete Named Graph support (i.e. use of
logical names to partition RDF data within Virtuoso's multi-model
dbms engine)
- Inference Engine (currently in use re. DBpedia via Yago and UMBEL)
- Host and exposes data from Drupal, Wordpress, MediaWiki, phpBB3
as RDF Linked Data via in-built support for PHP
runtime
-
Available as an EC2 AMI
- etc..
OpenLink Data Spaces functionality summary:
- Simple mechanism for Linked Data Web enabling yourself by giving you an
HTTP based User ID (a de-referencable
URI) that is linked to a FOAF based Profile page and OpenID
- Binds all your data sources (blogs, wikis, bookmarks, photos,
calendar items etc. ) to your URI so can "Find" things by only
remembering your URI
- Makes your profile page and personal URI the focal point of
Linked Data Web presence
- Delivers Data Portability (using data access by value or
data access by reference) across data
silos (e.g. Web 2.0 style social networks)
- Allows you make annotations about anything in your own Data Space(s) on the Web without exposure to
RDF markup
- A Briefcase feature that provides a WebDAV driven RDF Linked
Data variant of functionality seen in Mac OS X Spotlight and WinFS
with the addition of SPARQL compliance
- Automatically generates RDFa in
its (X)HTML pages
-
Blog, Wiki, WebDAV File Server, Shared
Bookmarks, Calendar, and other applications that look and feel like
Web 2.0 counterparts but emitt RDF Linked Data amongst a plethora
of data exchange formats
- Available as an EC2 AMI
- etc..
OpenLink Ajax Toolkit functionality summary:
- Provides binding to SQL, RDF, XML, and Web Services via Ajax
Database Connectivity Layer (you only need an ODBC, JDBC, OLE-DB, ADO.NET, XMLA Driver, or Web Service on the
backend for dynamic data access from Javascript)
- All controls are Ajax Database Connectivity bound (widgets get
their data from Ajax Database Connectivity data sources)
- Bundled with Virtuoso and ODS installations.
- etc.
OpenLink Data Explorer functionality summary
- Distills entities associated with information resource style
containers (e.g. Web Pages or files) as RDF Linked Data
- Exposes the RDF based Linked Data graph associated with information
resources (see the Linked Data behind Web pages)
- Ubiquity commands for invoking the above
- Available as a Hosted Service or Firefox
Extension
- Bundled with Virtuoso and ODS installations
- etc.
Note:
Of course you could have simply looked up OpenLink Software's FOAF based Profile page
(*note the Linked Data Explorer tab*), or simply passed the
FOAF profile page URL to a Linked Data aware client application
such as: OpenLink Data Explorer, Zitgist
Data
Viewer, Marbles, and Tabulator, and obtained information.
Remember, OpenLink Software is an Entity of Type: foaf:Organization, on the burgeoning Linked
Data Web :-)
