KEGG DGROUP contains structurally and functionally related groups of D number entries in KEGG DRUG. There are five types of drug groups. Chemical - grouped as identical chemical structures with minor variations of salts, hydration states, etc. Structure - grouped as similar chemical structures having the same skeleton, etc. Target - grouped by drug targets Class - drug classes often representing similar mechanisms of action Metabolism - grouped by substrates, inhibitors and inducers of drug metabolizing enzymes and transporters Chemical groups are often used for identifying essentially the same active ingredients of drugs in different countries.

Identifiers represent RNA-protein interaction entries with quantitative kinetic data in the Kinetic Data of Biomolecular Interactions for RNA-Protein database (KDBI-RP), which is an open-access database cataloging association rates, dissociation rates, and equilibrium dissociation constants for RNA-protein interactions.

The Clinical Research Information Service (CRIS) is a non-profit online registration system for clinical trials (researches) to be conducted in Korea. It has been established at the Korea Disease Control and Prevention Agency (KDCA) with support from the Ministry of Health and Welfare (MOHW). It joined the WHO International Clinical Trials Registry Platform (ICTRP) as 11th member of Primary Registry.

The International Clinical Trials Registry Platform, originally called International Standard Randomised Controlled Trial Number (ISRCTN) registry, is a primary clinical study registry recognised by the World Health Organisation (WHO) and the International Committee of Medical Journal Editors (ICMJE) that accepts all clinical research studies (whether proposed, ongoing or completed), providing content validation and curation and the unique identification number necessary for publication. All study records in the database are freely accessible and searchable. (from homepage)

The primary purpose of ISO 15926 is to provide a foundation ontology to support the integration and sharing of data related to the lifecycle of a process plant in such a way that it is consistent, unambiguous, and minimizing the number of ways something could be expressed. Further purpose of ISO 15926-14 is to meet needs for OWL 2 ontologies that are based on ISO 15926-2, that enable efficient reasoning and that capture lifecycle information. A specific purpose is to demonstrate lifecycle modelling through a representation of the lifecycle model of ISO/IEC 81346-1. Another specific purpose is to exemplify how this standard can be used to develop industrial ontologies through various real-world use cases from industry.

Since the introduction of ISO 639-3 in 2007, access to language information has increased tremendously. The code set initially adopted as ISO639-3:2007 was based on a harmonization of ISO 639-2 with the code set of SIL’s Ethnologue 15th edition and languages from Linguist List to form a comprehensive set of code elements for world languages. SIL International, the Language Coding Agency for 639-3, relies on the contributions of linguists, language coding experts, and language users around the world to maintain and improve the code set through the change request process defined in the ISO 639 standard.
