List of Informational attributes

TAXON 
A taxon is described by a name considered valid within the framework of EDAPHOBASE. Cross-references to different forms of synonyms exist as well as – partially – a (in the framework of EDAPHOBASE: exact) classification within a systematic tree.

RECORD / OBJECT DESCRIPTION 
The record or object descriptions contain the “actual” observation results (e.g., number of males / females / juveniles; abundances, etc.) and either describe the “taxon” (as an abstract concept) or the (concrete) individual assigned to a taxon (or a gender, developmental stage etc.).

SPECIFIC DESCRIPTION DATA OF SOURCE 
The list of what and where (i.e., pages, collection number) certain information on the taxon can be found in the source.

SAMPLING DESCRIPTION 
A sample description contains information about the observation, which can be described as a collection event (e.g., information regarding the collector, the sampling method, the observation date, etc.).

GEOGRAPHIC REFERENCE 
A geographic reference is essentially described by a descriptive name and its geographical coordinates.

SAMPLING SITE DESCRIPTION 
A sampling site description contains a list of parameters describing the locality (sampling site) in detail (e.g., physical, such as soil particle-size distributions; chemical, such as pH; or ecological and habitat type).

SPECIES DETERMINATION 
The species determination (for items in collections several are possible) must be listed separately. Here, particularely the determination literature used is noted. It is possible to compile statistics about who determines which objects and when.

PERSONAL DATA
These object types are not directly set in the data, but are linked to it.

PERSON
People predominantly occurring as authors in the literature. In addition, collectors and individuals determining objects in collections, are ‘persons’. Even institutions (such as a publisher, the owner of a collection) are collated in EDAPHOBASE as ‘persons’.

SOURCE
A source may be a literature reference (book, paper, …), a collection object or a “pure” observation (e.g., a table of observational data in the context of a project).

EXEMPLAR
Exemplars are:
in literature sources: the physically existing (personal) copies, for example, a book on a shelf, a paper in a reprint collection
in collections: the physically existing object; for collection objects, loans are connected to the specific exemplar

SYNONYM
To manage the synonymy relationships between taxonomic names, special fields and “roles” connected to the valid taxon name are required.
