n=E5got, har jag ljugit? Speciellt det d=E4r med vad som =E4r standard,

Web Resource Application Framework (WRAF) key features:

WRAF is primarily designed as a platform for:
=B7 Data-driven web applications with complex class hierarchies and
inter-resource relations, such as metadata repositories, topic
communities and intranets.
=B7 Applications collecting, processing and presenting information from
many sources, distributed over many processes.
=B7 Intelligent agents and robots.
=B7 Dynamic content, where the content selection and presentation is a
result of complex dependencies.

WRAF offers=20
=B7 an consistent interface to and between multiple information sources
=B7 the possibility of rich data and metadata modeling through inheritance
=B7 an open, standardized and extensible way of describing and exchanging
resources, inter- as well as intraorganizational.
=B7 a framework for RAD (Rapid Application Development) and realtime
system extension through schema remodeling.

WRAF is built upon
=B7 RDF, an open W3C (WWW Consortium) standard for distributed resource
modelling through DLG (Directed Labeled Graphs).
=B7 RDF-Schema, the W3C standard for schema modelling under RDF
=B7 RDF-XML, the W3C standard for expressing RDF data in XML.
=B7 RDF QDS, an query definition schema modelled in RDF.
=B7 RDF SDS - The Serialisation Definition Schema is used to describe
transformations between a RDF DLG and serialized formats, such as
RDF-XML, native XML, [X]HTML, WML, et.c.
=B7 WRAF XML SDS - A base SDS for expressing RDF as XML
=B7 WRAF [X]HTML SDS - A base SDS for expressing RDF resources as [X]HTML
=B7 RDF DB - An interface for storing and retrieving RDF DLG in relational
databases
=B7 WRAF API - The core functionality, exposing RDF models and interfaces.
WRAF IE - The Inference Engine enables applications that do not share
data definitions to identify and bridge RDF Schema incompatibilities.

Currently, all functionality is implemented as an UNIX service deamon
with a cgi/mod_perl client.

The RDF, RDF-XML and RDF-Schema are open W3C standards. The RDF DB, WRAF
API and WRAF IE are open source as per GNU Public License, and will be
given to CPAN upon completion. The RDF QDS and SDS will be submitted as
standards proposals upon completion.
