Notice dated 26 May 2008: Registration of resources in the PORTAL-DOORS system now available at
GTG
Registrar.
The PORTAL-DOORS infrastructure system of networked registries and directories has
been designed for the semantic web and grid as an extended analogue of the IRIS-DNS
system for the original web. The Domain Name System (DNS) of directories and the
Internet Registry Information System (IRIS) of registries have been well established
for registering domain names and publishing their associated internet addresses.
Analogously, the Domain Ontology Oriented Resource System (DOORS) and Problem Oriented
Registry of Tags And Labels (PORTAL) have been designed to register resource labels
and tags and publish their locations and descriptions (see
PORTAL-DOORS paper).
This web site will host a collaborative open source project for the ongoing development
and implementation of the PORTAL-DOORS infrastructure system. PORTAL-DOORS has been
designed to implement the following principles and requirements:
- A distributed network of registries and directories for resource metadata oriented
by problem domain or specialist community rather than by technology format of the
resource.
- A hierarchical system enabling local independence of communities while simultaneously
maintaining global compatibility for communication between and search amongst different
communities.
- A hybridized architecture with XML Schemas serving the original web and RDF/OWL
ontologies serving the semantic web to bridge and transition from the original web
to the semantic web.
- Decentralization and democratization to promote evolutionary adoption of schemas
and ontologies (ie, survival of the fittest, not necessarily the first).
- Hierarchical authorities and globally unique identifiers to prevent namespace conflicts
for naming of resources.
- Designed to accomodate any kind of resource, whether abstract or concrete, offline or online, without
any requirement to be either a semantic resource or a non-semantic resource with
a semantic description.
- Supported with cross-references to other systems whether legacy or contemporaneous.
For further details and complete discussion, please refer to the
PORTAL-DOORS paper.
