                                             <sea:Content>See DateType for general usage.  Identification dates are commonly unknown (element optional), or incompletely known.  Missing information reduces precision of the date; i.e., known only to Year or Year and Month.  Sometimes identification dates are inferred from a researcher's visit or duration of a loan.</sea:Content>

                                             <sea:EditorialNotes>We probably don't need IdentificationDate to support the full range of date time elements that are present in the DateTimeType.  It's hard to imagine a realistic case where time of day could be relevant to an identification.  If year is unkown, simple text will provide the only function needed -- human readability of the existing information.  (Retrieval and sorting by interval in the annual cycle, as we want to support with CollectionDate, is irrelevant in this case.)  A single ISO 8061 Date field, along with an IdentificationDateAltText is sufficient to cover the needs around this concept.  -- Blum, 2002-12-10</sea:EditorialNotes>

                                             <sea:EditorialNotes>Issue 1:  I think IdentificationReference and IdentificationSource have reversed names and semantics.  Source should refer to where the identification is recorded, while "reference" should refer to a publication used to make the determination, but not containing the identification.  Issue 2:  Should we recommend that "field tag", and "determination slip" be recorded when something "usual" is the IdentificationReference.  In my experience, IdentificationReference is not recorded in cases that are typical (e.g., det.slip, field tag). The reference is recorded only when the reference is a published work and when that specimen's identity is a prominent feature of the publication.  Simply being listed in the material examined section would not be siginicant enough to warrant the effort of entering a special IdentificationSource record. (Listing in a material examined section would warrant a general bibliographic citation for a Unit.)</sea:EditorialNotes>

Structure allows for full analysis of stratigraphy e.g. to allow fossils in collections to be sorted by period and zone. Also allows for free text terms when their staus is unknown or for more full descriptions of stratigraphy of site.</sea:Comments>

(b) Exposure, i.e. an indication of the degree of exposure of a collecting or recording site - (often used with marine shore recording) e.g. sheltered. (c) Hydrological features of the site or collection point. (d) Description of the topography either related to a site as a feature or recorded as part of a sample (i.e attaches info to recorders and date).  (e) Other geomorphological features.  </sea:Comments>
