Linguistic Linked Open Data

LLOD

Subject(s)

The Linguistic Linked Open Data cloud is a collaborative effort pursued by several members of the OWLG, with the general goal to develop a Linked Open Data (sub-)cloud of linguistic resources. The diagram is inspired by the Linking Open Data cloud diagram by Richard Cyganiak and Anja Jentzsch, and the resources included are chosen according to the same criteria of openness, availability and interlinking. Although not all resources are already available, we actively work towards this goal, and subsequent versions of this diagram will be restricted to openly available resources. Until that point, please refer to the diagram explicitly as a "draft".

Chempound

a Web2.0-inspired repository for physical science data

Subject(s)
Content type(s)
Country
Chempound is a new generation repository architecture based on RDF, semantic dictionaries and linked data. It has been developed to hold any type of chemical object expressible in CML and is exemplified by crystallographic experiments and computational chemistry calculations. In both examples, the repository can hold >50k entries which can be searched by SPARQL endpoints and pre-indexing of key fields. The Chempound architecture is general and adaptable to other fields of data-rich science. The Chempound software is hosted at http://bitbucket.org/chempound and is available under the Apache License, Version 2.0

Rhea

Rhea is a freely available and comprehensive resource of expert-curated biochemical reactions. It has been designed to provide a non-redundant set of chemical transformations for applications such as the functional annotation of enzymes, pathway inference and metabolic network reconstruction. There are three types of reaction participants (reactants and products): Small molecules, Rhea polymers, Generic compounds. All three types of reaction participants are linked to the ChEBI database (Chemical Entities of Biological Interest) which provides detailed information about structure, formula and charge. Rhea provides built-in validations that ensure both mass and charge balance of the reactions. We have populated the database with the reactions found in the enzyme classification (i.e. in the IntEnz and ENZYME databases), extending it with additional known reactions of biological interest. While the main focus of Rhea is enzyme-catalysed reactions, other biochemical reactions (including those that are often termed "spontaneous") also are included.
