A comprehensive database of human H/ACA and C/D box snoRNAs.

Contains identifiers for human small nucleolar RNAs (snoRNAs) from snoDB, an interactive database of human small nucleolar RNAs (snoRNAs) that includes up-to-date information on snoRNA features, genomic location, conservation, host gene, snoRNA–RNA targets and snoRNA abundance and provides links to other resources.

The SNCTP (Swiss National Clinical Trials Portal) is the portal where clinical trials in Switzerland are published. It contains data from two sources: from BASEC, the national platform for submitting applications for research projects to ethics committees, and from the ICTRP (the WHO International Clinical Trials Registry Platform), which covers the 17 primary registries worldwide. The ICTRP clinical trials shown on the SNCTP are limited to those conducted in Switzerland; there is also an option to display trials conducted in one of Switzerland's neighbouring countries.

Theoretical explanation of a purely spatial ontology supporting snapshot views of the world at successive instants of time, as part of a modular ontology of the dynamic features of reality.

Documentation of SMILES (Simplified Molecular Input Line Entry System), a line notation (a typographical method using printable characters) for entering and representing molecules and reactions.

SMIDs (Small Molecule Identifiers) represent gene-style identifiers for small molecules newly identified in C. elegans and other nematodes. SMIDs aim to make life easier for describing biogenic small molecules in metabolomic and genomic applications.

The secondary metabolism collaboratory is a database for secondary metabolite biosynthetic gene clusters. This prefix represents identifiers for bacteria and archaea sources linked to their associated set of biosynthetic gene clusters (BGCs).

The secondary metabolism collaboratory is a database for secondary metabolite biosynthetic gene clusters. This prefix represents identifiers for individual biosynthetic gene clusters (BGCs) linked to their corresponding bacterial or archaeal source.

The Sri Lanka Clinical Trials Registry (SLCTR) is a Registry for clinical trials involving human subjects, conducted in Sri Lanka or overseas. The SLCTR is a Primary Registry linked to the Registry Network of the International Clinical Trials Registry Platform of the WHO (WHO-ICTRP). It is a not-for-profit Registry, with free and open access to researchers, clinicians, and the general public. (from homepage)

The Simple Knowledge Organization System (SKOS) is a common data model for sharing and linking knowledge organization systems via the Semantic Web. SKOS-XL defines an extension for the Simple Knowledge Organization System, providing additional support for describing and linking lexical entities.This document provides a brief description of the SKOS-XL vocabulary.

SKOS-Thes: An extension to SKOS based on the ISO 25964 data model. The ISO 25964 standard, published in 2011, covers all aspects of developing thesauri and setting up mappings across vocabularies to encourage high quality information retrieval across networked resources. [from https://www.dublincore.org/specifications/skos-thes/]

SKOS is an area of work developing specifications and standards to support the use of knowledge organization systems (KOS) such as thesauri, classification schemes, subject heading lists and taxonomies within the framework of the Semantic Web

SKIP is aiming to promote the exchange of information and joint research between researchers by aggregating various information of stem cells (iPS cells, iPS cells derived from patients, etc.) to stimulate research on disease and regenerative medicine.

A modern method of records management and an automated cross-referenced subject index for accurate and comprehensive information retrieval developed by the US FDA's Bureau of Foods

Extends the SIOC Core Ontology (Semantically-Interlinked Online Communities) by defining subclasses and subproperties of SIOC terms.

Mappings from SIOC to SWAN, with a small number of aux terms

Extends the SIOC Core Ontology (Semantically-Interlinked Online Communities) by defining basic information on community-related web services.

Semantically-Interlinked Online Communities, or SIOC, is an attempt to link online community sites, to use Semantic Web technologies to describe the information that communities have about their structure and contents, and to find related information and new connections between content items and other community objects. SIOC is based around the use of machine-readable information provided by these sites.

A vocabulary of argumentation predicates for SIOC

An ontology of predicates for actions in SIOC

Extends the SIOC Core Ontology (Semantically-Interlinked Online Communities) by defining basic information on permissions and access rights.

SILVA is a resource of aligned ribosomal RNA (rRNA) gene sequences for Bacteria, Archaea, and Eukaryotes. It assigns internal, auto-incremented integer identifiers to taxa. However, these identifiers are not persistent nor unique - if the label for a taxon is changed, it assigned a new identifier and the old identifier is removed.

Identifiers for relationships between proteins and complexes, along with their type and provenance

Sigma Aldrich is a life sciences supply vendor.

Service Categories (KCDB). This service shows the related service categories for the Key Comparisons DataBase (KCDB) by quantity.

Ontology, part of the SI Reference Point, covering measurement units (SI base units and SI units with special names) and prefixes.

This shapes graph can be used to validate SHACL shapes graphs against a subset of the syntax rules.

A vocabulary used in tandem with SHACL for representing node shapes

The Shape Expressions (ShEx) language describes RDF nodes and graph structures. A node constraint describes an RDF node (IRI, blank node or literal) and a shape describes the triples involving nodes in an RDF graph. These descriptions identify predicates and their associated cardinalities and datatypes. ShEx shapes can be used to communicate data structures associated with some process or interface, generate or validate data, or drive user interfaces.

Sharkipedia is an open source research initiative to make all published biological traits and population trends on sharks, rays, and chimaeras accessible to everyone.

A language for validating RDF graphs against a set of conditions
