New Web Core

• Metadata definition, dissemination and
  development of applications
• Document Type Definitions generalized through
  Resource Definition Format (RDF/XML)
• Name Spaces
• Ontologies
• Seamless access to heterogeneous databases
  through the constitution of common objects
• Inference languages that act on the RDF

  alternative NameSpaces
• XML
• scripting language that can be used to define
  specific communities marking languages
• databases, catalogs and other services of
  specific communities can be integrated

standards for networking

• Metadata is data associated with objects which
  relieves their potential users of having to have
  full advance knowledge of their existence or
  charasteristics (Dempsey and Heery 1998)
• Lets make things simple
• Data about data (Weibel 1997, et alias)
• Metadata supports the generation and access to
  distributed resources by
• Provision of common semantic and enabling
• Interoperability of technical systems

• DC Dublin Core is a set of 15 Metadata
  elements widely agreed and implemented Title,
  Creator, Subject, Description, Publisher,
  Contributor, Data Type, Format, Identifier,
  Source, Language, Relation

The overall architecture and language

• RDF provides a simple data model for
  representing formal semantics of information,
  i.e. meta-information.
• RDF Schema defines a simple ontology modeling
  language on top of RDF that can be used to define
  vocabulary and structure of meta information.
• OIL adds a simple Description Logic to RDF
  Schema It allows to define axioms that logically
  describe classes, properties, and their
  hierarchies.
• Currently, a sub dialect of OIL called DAMLOIL
  is the starting point of a web ontology language
  standardization group of the W3C.

standards for networking

• Jewish Networking Thesaurus
• Thesaurus is a tool for vocabulary control
  restricts vocabulary so it is easier to predict
  what words might have been used to index a
  concept
• Improve quality of retrieval by guiding indexers
  and searchers
• Enables access to resources by searching and
  retrieval browsing documents on a nominated
  topic getting suggestions in the context
  filtering and alerting
• Alerting to new material requires individual
  specification and the subject category, chosen
  from a vocabulary facilitates this.
