| - There is some question as to what types of ontologies are required for topical annotations and signature annotations. There may be one overall ontology, in which both styles of annotation draw terms from, or it may be convenient to have separate ontologies for each style. The ontology for topical annotations may be inherently more general, representing one or more simple classification axes that allow users to label actors and data with relevant terms. To illustrate, an actor that calculates the Shannon-Weiner index might be labeled as a "BiodiversityIndex" and a model that generates spatially explicit maps of species distributions might be labeled as a "SpatialSpeciesDistributionModel."[#1] The signature ontology would specifically be used to label the semantic types of data that are contained within a data set or that flow between two or more actors. Thus, this ontology would contain terms that are concretely tied to real-world measurements as represented by data. For example, the annotation for a particular column in a biodiversity data set might be "PsychotriaLimonensisArealDensity" (it would also have a structural type describing units, etc). A particular "BiodiversityIndex" actor might take input data with the type "SpeciesArealDensity", and the ontology would allow us to deduce that the Psychotria limonensis data is semantically compatible with the actor's input requirement. |
