Identifies the type of aggregation used to combine related categories, usually within a common branch of a hierarchy, to provide information at a broader level than the level at which detailed observations are taken. (From: The OECD Glossary of Statistical Terms)

Describes the entity being analyzed in the study or variable. This vocabulary can also be used to describe the unit of observation, which is the unit being observed, or from which data are collected. The unit of observation can be the same as, or different from the unit of analysis.

The Enzyme Nomenclature (also known as the Enzyme Commission Code) is a species-agnostic controlled vocabulary for specific enzymes and an associated hierarchical classification into 7 main categories. The Enzyme Nomenclature is maintained by the [Nomenclature Committee](https://iubmb.org/about/committees/nomenclature-committee/) of the International Union of Biochemistry and Molecular Biology (IUBMB). A detailed history of the nomenclature since the 1950s can be found [here](https://iubmb.qmul.ac.uk/enzyme/history.html). There are few notable resources providing access to the Enzyme Nomenclature: <table class="table table-striped"><thead><tr><th>Website</th><th>Homepage</td><th>Notes</td></tr></thead><tbody><tr><td>ExplorEnz</td><td><a href="https://www.enzyme-database.org">https://www.enzyme-database.org</a></td><td>This is the resource officially recommended by IUBMB</td></tr><tr><td>IUBMB (via by Queen Mary)</td><td><a href="https://iubmb.qmul.ac.uk/enzyme">https://iubmb.qmul.ac.uk/enzyme</a></td><td>This is a web-based version of the <a href="https://archive.org/details/enzymenomenclatu0000inte_d6c2">1992 publication</a>.</td></tr><tr><td>IntEnz</td><td><a href="https://www.ebi.ac.uk/intenz">https://www.ebi.ac.uk/intenz</a></td><td>Shutdown in 2024</td></tr><tr><td>ExPaSy</td><td><a href="https://enzyme.expasy.org">https://enzyme.expasy.org</a></td></tr><tr><td>EnzymePortal</td><td><a href="https://www.ebi.ac.uk/enzymeportal">https://www.ebi.ac.uk/enzymeportal</a></td><td></td></tr></tbody></table>

The Electron Microscopy (EM) Glossary is a widespread community effort to harmonize terminology in the electron and ion microscopies. It is created in a not-for profit collaboration between academic and non-university research institutions including domain and metadata experts. It provides harmonized terminology for application level semantic artifacts to source from and align with. [from homepage]

The EOL ontology describes environmental conditions of livestock farms. More specifically, it describes the feeding modalities, the environment, the structure of livestock farms and rearing systems.

European Science Vocabulary (EuroSciVoc) is the taxonomy of fields of science based on OECD's 2015 Frascati Manual taxonomy. It was extended with fields of science categories extracted from CORDIS content through a semi-automatic process developed with Natural Language Processing (NLP) techniques. (from homepage)

EuroVoc is the EU's multilingual and multidisciplinary thesaurus. It contains keywords, organized in 21 domains and 127 sub-domains, which are used to describe the content of documents in EUR-Lex. [from homepage]
