Edits to 'https://fairsharing.org/FAIRsharing.17zapb' by 'The FAIRsharing Team' at 22:44, 30 Nov 2016 (approved): 'description' has been modified: Before: The Xenopus Anatomical Ontology (XAO) describes Xenopus anatomy and embryological development using a 'controlled vocabulary' of anatomy terms that are organized in an hierarchy with a graphical structure. XAO terms describe gene expression, and the XAO is constantly being updated in response to the latest published Xenopus research. The XAO contains 1000's of terms and relationships. Each anatomical system (eg; central nervous system|alimentary/biliary system)|tissue and structure (eg; neural fold|mesoderm|blastpore) and many cell types (eg.|clilated epidermal cell|migrating neural crest cell) are separate terms; each term is fully defined and related to other terms by is_a|part_of |develops_from and develops_into relationships. All growth/life cycles stages (eg blastula|gastrula|tadpole) and Nieuwkoop & Faber stages (NF stages) are also XAO terms (e.g.|gastrula stages include NF stage 10 to NF stage 12.5). This allows the timing of anatomical development to be indicated by starts_during and ends_during relationships with NF stages. After: The Xenopus Anatomical Ontology (XAO) describes Xenopus anatomy and embryological development using a 'controlled vocabulary' of anatomy terms that are organized in an hierarchy with a graphical structure. XAO terms describe gene expression, and the XAO is constantly being updated in response to the latest published Xenopus research.

Bgee is a database to retrieve and compare gene expression patterns in multiple animal species, produced from multiple data types (RNA-Seq, Affymetrix, in situ hybridization, and EST data). Bgee is based exclusively on curated "normal", healthy, expression data (e.g., no gene knock-out, no treatment, no disease), to provide a comparable reference of normal gene expression. Bgee produces calls of presence/absence of expression, and of differential over-/under-expression, integrated along with information of gene orthology, and of homology between organs. This allows comparisons of expression patterns between species.
Xenopus laevis and tropicalis biology and genomics resource
Xenbase is the model organism database for Xenopus laevis and X. (Silurana) tropicalis. It contains genomic, development data and community information for Xenopus research. It includes gene expression patterns that incorporate image data from the literature, large scale screens and community submissions.
The Open Biological and Biomedical Ontology (OBO) Foundry is a collective of ontology developers that are committed to collaboration and adherence to shared principles. The mission of the OBO Foundry is to develop a family of interoperable ontologies that are both logically well-formed and scientifically accurate. To achieve this, OBO Foundry participants voluntarily adhere to and contribute to the development of an evolving set of principles including open use, collaborative development, non-overlapping and strictly-scoped content, and common syntax and relations, based on ontology models that work well, such as the Gene Ontology (GO). The OBO Foundry is overseen by an Operations Committee with Editorial, Technical and Outreach working groups.
