UMBEL (Upper Mapping and Binding Exchange Layer) has two purposes. Its first purpose is to provide a general vocabulary (the UMBEL "vocabulary") of classes and predicates for describing domain ontologies, with the specific aim of promoting interoperability with external datasets and domains. The second purpose is to provide a coherent framework of broad subjects and topics (the UMBEL "reference concepts"), suitable as binding nodes for mapping relevant Web-accessible content, also with the specific aim of promoting interoperability and to reason over a coherent reference structure and its linked resources. UMBEL presently has about 28,000 of these reference concepts drawn from the Cyc knowledge base, which are organized into more than 30 mostly disjoint SuperTypes.

directory of Semantic Web Services. We hope that this web page will provide semantic web service investigators with an index to projects, standards and bibliographical references of semantic web service proposals.

RDF is a standard model for data interchange on the Web. RDF has features that facilitate data merging even if the underlying schemas differ, and it specifically supports the evolution of schemas over time without requiring all the data consumers to be changed. RDF extends the linking structure of the Web to use URIs to name the relationship between things as well as the two ends of the link (this is usually referred to as a "triple"). Using this simple model, it allows structured and semi-structured data to be mixed, exposed, and shared across different applications.

Wiki contains a collection of tool references that can help in developing Semantic Web applications. These include complete development environments, editors, libraries or modules for various programming languages, specialized browsers, etc. The goal is to list such tools and not Semantic Web applications in general.

The OBO Foundry is a collaborative experiment involving developers of science-based ontologies who are establishing a set of principles for ontology development with the goal of creating a suite of orthogonal interoperable reference ontologies in the biomedical domain. The groups developing ontologies who have expressed an interest in this goal are listed below, followed by other relevant efforts in this domain.

The LOV dataset contains the description of RDFS vocabularies or OWL ontologies defined for and used by datasets in the Linked Data Cloud. Whenever available each vocabulary includes references to the datasets using it, in particular those listed in CKAN.

Wikicat is the bibliographic catalog used by the Wikicite and WikiTextrose projects. It will be implemented as a Wikidata dataset using a datamodel design based upon IFLA's Functional Requirements for Bibliographic Records: final report (FRBR) [1], the various ISBD standards, the Library of Congress's MARC 21 specification, the Anglo-American Cataloguing Rules' The Logical Structure of the Anglo-American Cataloguing Rules and Resource Description and Access (RDA), and the International Committee for Documentation (CIDOC)'s Conceptual Reference Model (CRM)[2]. The history and inter-relation of these various cataloging standards is described in RDA presentations.

"In addition to the classic "Web of documents" W3C is helping to build a technology stack to support a "Web of data," the sort of data you find in databases. The ultimate goal of the Web of data is to enable computers to do more useful work and to develop systems that can support trusted interactions over the network. The term "Semantic Web" refers to W3C's vision of the Web of linked data. Semantic Web technologies enable people to create data stores on the Web, build vocabularies, and write rules for handling data. Linked data are empowered by technologies such as RDF, SPARQL, OWL, and SKOS."

Taking the reference from points in this post will surely help you to initiate the process of domain name transfer with ease, as well as you will be safe from paying unforeseen costs.

Tagpedia is a semantic reference useful to create sense-based descriptions of resources over the Web. In this way it wants to provide support to a better organization and access to semantically described Web contents in order to improve the management and the search for useful information. The initial contents of Tagpedia has been extracted mining Wikipedia.

Web IDs are world-wide "strong identifiers" that you and your software can use to precisely identify and distinguish concepts, even if they share the same names. For example: "Jaguar" can be used to refer to several distinct concepts (the animal, the car company, the musical artist, etc.) but each of them have different Web IDs. Whereas keywords are ambiguous, Web IDs are precise.

The Web of Data has many equivalent URIs. This service helps you to find co-references between different data sets. Enter a known URI, or use Sindice to search first.

"Friend of a friend (FOAF) is a phrase used to refer to someone that one does not know well, literally, a friend of a friend. In some social sciences, the phrase is used as a half-joking shorthand for the fact that much of the information on which people act comes from distant sources (as in "It happened to a friend of a friend of mine") and cannot be confirmed. It is probably best known from urban legend studies, where it was popularized by Jan Harold Brunvand. It was first published by Rodney Dale in his 1978 book The Tumour in the Whale, in which he discussed the "FOAFtale". The rise of social network services has led to increased use of this term."

URLs (Persistent Uniform Resource Locators) are Web addresses that act as permanent identifiers in the face of a dynamic and changing Web infrastructure. Instead of resolving directly to Web resources, PURLs provide a level of indirection that allows the underlying Web addresses of resources to change over time without negatively affecting systems that depend on them. This capability provides continuity of references to network resources that may migrate from machine to machine for business, social or technical reasons.
