Named attributes may be assigned to quite a number of object types in BSCW. Some have a predefined set of attributes (apart from name and description):
o Documents may be described and classified using attributes from a subset of the Dublin Core Metadata Element Set (such as “(DC) Title”, “(DC) Author” or “(DC) Language”). If support for storage and exchange of document encryption keys has been activated for your BSCW server, there are two additional metadata attributes for documents: “Key” and “Recipients”. These attributes are meant for documents with an according MIME type containing encryption keys. The “Key” attribute is meant for a description of the key and the “Recipients” attribute should list the users to whom the key has been sent, if any. For details, see 9.5.3 BSCW Desktop client and the online help of BSCW Desktop.
o Contacts are described by numerous attributes concerning name, address, phone numbers, affiliation etc.
o Tasks may be classified by another set of attributes like customer, contact, location, category etc.
Note that the precise set of named metadata attributes may be configured differently for your BSCW server. Contact your BSCW administrator.
A first set of attributes may be assigned when creating an object. In general, attributes may be set in the ‘Attributes’ section of the object creation form. Enter values into the fields provided. Values of date attributes should be complete, i.e. should contain year, month and day. Best practice for specifying users is to enter their user names as they are commonly shown in BSCW.
Some attributes allow specifying multiple values by clicking next to the input field. You may delete values by clicking next to the value field.
In order to assign values to attributes or to change values already assigned, you may
• select Change Properties in the action menu of the object concerned and go to the section ‘Attributes’ of the action form. You may also delete values of attributes that you do not need any longer.
If your BSCW server is configured accordingly, you may define your own attributes by entering the name and optionally the value of a self-defined attribute into the two empty fields below ‘Define your own attributes’. Click on [New attribute] to enter further user-defined attributes. User-defined attributes must have unique names. They are deleted by deleting their name.
All attributes with values are shown below the description of an object in the folder listing, user-defined attributes are shown even if they have no value. If the view options are set so that no descriptions are shown or only shown in compact form, attributes will appear as tooltips of either the icon or the one-line description, respectively. Also, all attributes are shown on the info page of an object.
All attributes including user-defined attributes may be used in BSCW searches. The search form offers to include all attributes as search criteria.
