Metadata Profile

UC_FAC_MD_01 Create metadata profile

Status/Schedule

• Status: in specification
• Schedule:

Description
A medatada profile can only be created during the creation of a collection (see UC_FAC_COL_01 Create collection). Therefore it is always in the same state than the corresponding collection.
The user has two different options:

1. To create a new MD profile
   • A MD profile consists of Name, Description, Owner, Owner.Organization (all values inherited from the corresponding collection), and attributes (complex, mandatory, one-unbounded)
   • An attribute consists of
     1. type (list, mandatory, once) e.g. date, geonames, string, integer, cone-person
     2. label (list/string, mandatory, once) either defined by the user himself or chosen out of an list of already existing attributes
     3. cardinality (list, mandatory, once): once / multiple
     4. obligation (list, mandatory, once): mandatory / optional
     5. (optional) a possibility to define a list of allowed values (one text field for each value)
2. To use an already available MD profile as template
   1. The system displays a list of all available metadata profiles.
   2. (Optionally) The user wants to view the details of one selected metadata profile.
   3. The user can select one of the already existing md profiles (the system creates a copy of the md profile).
   4. The user can modify all metadata (the inherited ones from the collection will automatically change to the collection which uses the template) and attributes of the profile, can create new attributes or delete already existing attributes.

UC_FAC_MD_02 Edit metadata profile

Status/Schedule

• Status: in specification
• Schedule:

Pre-Condition

• One MD profile is selected

Description
A medatada profile can only be edited during the editing of a collection (see UC_FAC_COL_02 Edit collection).Therefore it is always in the same state than the corresponding collection.

1. The user can modify the metadata of the profile.
2. The user can modify all attributes of the profile and can create new attributes or delete already existing attributes.
   • When deleting already available attributes, all values of these attributes will be deleted, too. Therefore the system displays a warning message, where the number of values, that will be deleted, is displayed.
3. The user can modify the pre-define values for one or more attributes, can delete them or ad new values.
   • When deleting pre-defined values for one or more attributes, these values will be deleted also in the metadata sets of all pictures that use these values. Therefore the system displays a warning message, where the number of values, that will be deleted, is displayed.

Description

1. The system displays an information message which says how many pictures are currently selected. Further on, there must be a possibility to view all the selected pictures.
2. The whole metadata profile for the collection of the selected pictures is displayed.
3. The users can define one or more metadata values for all the selected pictures.
   • When only one picture is selected, already available metadata values will be displayed as pre-filled in.
   • When the selected pictures have one or more metadata values in common, this value(s) will be displayed as pre-filled in.
4. After saving, the system displays a confirmation message and assigns the defined metadata values to the pictures.
   • When one or several picture(s) already have a metadata value in one or more of the chosen fields, this value(s) will automatically be overwritten by the new value(s).

Comments

• It could happen that more than one user tries to edit the metadata of the same picture(s) at the same time. To avoid confusion about this, the system has to display a message.
