DCAT is an RDF vocabulary designed to facilitate interoperability between data catalogs published on the Web. This document defines the schema and provides examples for its use. By using DCAT to describe datasets in data catalogs, publishers increase discoverability and enable applications easily to consume metadata from multiple catalogs. It further enables decentralized publishing of catalogs and facilitates federated dataset search across sites. Aggregated DCAT metadata can serve as a manifest file to facilitate digital preservation.
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.
DataCatalogs.org aims to be the most comprehensive list of open data catalogs in the world. It is curated by a group of leading open data experts from around the world - including representatives from local, regional and national governments, international organisations such as the World Bank, and numerous NGOs.
"DARPA Open Catalog, which contains a curated list of DARPA-sponsored software and peer-reviewed publications. DARPA funds fundamental and applied research in a variety of areas including data science, cyber, anomaly detection, etc., which may lead to experimental results and reusable technology designed to benefit multiple government domains.

"nitiated by the Library of Congress, BIBFRAME provides a foundation for the future of bibliographic description, both on the web, and in the broader networked world. This site presents general information about the project, including presentations, FAQs, and links to working documents. In addition to being a replacement for MARC, BIBFRAME serves as a general model for expressing and connecting bibliographic data. A major focus of the initiative will be to determine a transition path for the MARC 21 formats while preserving a robust data exchange that has supported resource sharing and cataloging cost savings in recent decades."
"The Global Database of Events, Language, and Tone (GDELT) is an initiative to construct a catalog of human societal-scale behavior and beliefs across all countries of the world, connecting every person, organization, location, count, theme, news source, and event across the planet into a single massive network that captures what's happening around the world, what its context is and who's involved, and how the world is feeling about it, every single day."
This website gives an overview of Linked Data sources cataloged on Data Hub and their completeness level for inclusion in the LOD cloud. It furthermore offers a validator for your Data Hub entry with step-by-step guidance.
"This document describes an ontology for publishing Linked Open Data (LOD) in the Open Data Web. The initial ontology is being designed for implementing CC licensed data in the Union Catalog of Digital Archives Taiwan . However, the core model of the ontology is flexible and adaptable for other uses in curating, publishing and reusing their data according to users' context. ."
"The VIAF™ (Virtual International Authority File) combines multiple name authority files into a single OCLC-hosted name authority service. The goal of the service is to lower the cost and increase the utility of library authority files by matching and linking widely-used authority files and making that information available on the Web."
