Stable identifier

Stable identifiers are generated from a basic URL and the IDs from the database. To set the basic URL select Administration - Stable identifier ... from the menu. A window as shown below will open, where you can set the basic URL for the stable identifier either for the whole database or for every project. With the button you can copy the current URL to all projects in the list.

The Test button creates a QR code for the URL as shown above using a google api (http://chart.apis.google.com). The stable identifier consits of the basis address as set above, followed by the part that identifies the object in the database as shown in the examples below. For an introduction see a short tutorial .

	Table	Stable identifier
	Specimen:	http://id.snsb.info/snsb/Collection_SNSB/312	= [Server]/[Instance]/[Alias for database]/[CollectionSpecimenID]
	Unit:	http://id.snsb.info/snsb/Collection_SNSB/312/789	= [Server]/[Instance]/[Alias for database]/[CollectionSpecimenID]/[IdentificationUnitID]
	Part:	http://id.snsb.info/snsb/Collection_SNSB/312/789/283	= [Server]/[Instance]/[Alias for database]/[CollectionSpecimenID]/[IdentificationUnitID]/[SpecimenPartID]
	Collection:	http://id.snsb.info/snsb/Collection_SNSB/Collection/23	= [Server]/[Instance]/[Alias for database]/[Table]/[CollectionID]
	Transaction:	http://id.snsb.info/snsb/Collection_SNSB/Transaction/4	= [Server]/[Instance]/[Alias for database]/[Table]/[TransactionID]

In the examples above http://id.snsb.info is the server, snsb is the instance on the server that may correspond to an organization etc. like ZSM or SMNK. Collection_SNSB is an alias for the database corresponding to the name of the database without the leading string Diversity. The following numbers point on the keys of the datasets in the main tables. The last two examples point to separate tables within the database and the following number correspond to the key for these tables.

An additional id service is necessary to make direct use of the stable identifiers. This id service redirect a given stable identifier to another web-page which shows data about the identifier. This can be HTML or xml-rdf according to the CETAF recommendations. The id service needs further information to redirect to those websites. For the redirection to a BioCase-Provider installation or a xml-rdf-service, the information can be retrieved from the main database. The necessary roles and logins for this id service can be generated by pressing the button at the buttom of the window. This buttom will not be visible if the corresponding roles etc. already do exist.
