In the botanical world of duplicate specimens and gifting of specimens to a specialist in exchange for a determination, a plant specimen can have multiple institutions actually annotated on it and therefore multiple institutionIDs potentially associated with it. Does DwC have a way to distinguish multiple institutionIDs for a specimen - e.g. original collecting institution and current repository institution?
Many bits are there, some bits aren't. The occuranceID is a GUID for the duplicate set (except untill we get the duplicate sets sorted out, everyone is going to be serving distinct occuranceIDs for each sheet in the set. There isn't a property to hold GUIDs for specimens, so we are left with the hopefully unique DarwinCore doublet of collectionID/collectionCode and catalogNumber (under the AppleCore guidance, we can ignore institutionCode/institutionID for the most part in botany, as herbarium acronyms are placed in collectionCode and GUIDs for herbaria are placed in collectionID). Available for trying to cluster duplicates are recordedBy for the collector name and recordNumber for the collector's number. Once we do have sets of duplicates linked with occurranceID, we don't, as you point out, have any way to determine which collectionID was the collection from which the duplicate set was distributed.

Hi Aaike,
The institutionID is definitely meant to be a GUID, and as such would not likely be of much use within an institutional database, where the institutionID would likely be the same for every record. Instead, it is meant to identify an institution in a persistent, hopefully resolvable way, where resolution would be able to give more information about the identified institution.
Identifiers for institutions do exist. An example is urn:lsid:biocol.org:col:34777, the institutionID in the Biodiversity Collections Index for the University of California Berkeley Museum of Vertebrate Zoology (MVZ), within which there are several collections, each with its distinct collectionID, such as urn:lsid:biocol.org:col:34818 for the Herpetology Collection at the MVZ.
The IDs are useful to provide the possibility of a link to other information that may not be shared in original record. They are also useful to distinguish the institutions and collections from each other. For example, MVZ is the acronym used for the Institution as a whole where the collections are housed, and it is also used independently by each of the collections when specimens are cited in literature. In other words, the institutionCode (MVZ) is not distinct from the collectionCodes (MVZ), and the collectionCodes within the institution are not unique (all MVZ). The IDs are meant to overcome this and other problems of reference and uniqueness.
I hope that helps,
John

Dear all,
While composing a template and recommendations for the Darwin Core fields to supply for the BioFresh project http://www.freshwaterbiodiversity.eu/, similar to what Peter Desmet did for herbaria in Apple Core http://code.google.com/p/applecore/, I came across a number of terms which I haven't yet completely understood and hope to get some feedback on from this community.
Two of these terms are:
InstitutionCode - InstitutionID http://rs.tdwg.org/dwc/terms/institutionCode - http://rs.tdwg.org/dwc/terms/institutionID
The name (or acronym) in use by the institution having custody of the object(s) or information referred to in the record. / An identifier for the institution having custody of the object(s) or information referred to in the record.
I guess that the latter term is supposed to be a DOI/GUID for the institute, but am wondering if there is such a thing or whether this field is rather for internal database purposes?
Any advise would be appreciated!
