Record Builder and Constant Data
Contents Document
Conventions Beginning with SiteSearch 4.1.2, you can make constant data available to metadata specialists who create and edit records in local databases using OCLC Database Builder's Record Builder application. You can define constant data for any database based on a Dublin Core (DC) or MARC Catalog database framework. You can create constant data values for any of the elements on a DC workform or the fields on a MARC workform, as displayed on Record Builder's Edit Record screen.
In Record Builder, constant data refers to predefined values for some elements (fields) on a data entry workform. You generally define constant data for elements that have the same value for many records in a database. For example, if many of the items being cataloged in a local DC database have the the same source, you may wish to provide a constant data value for the Source element so metadata specialists do not have to enter this value manually for every record. Where Does Constant Data Reside? You define constant data in an .xml file. The database frameworks shipped with Record Builder all include the word "constant" in the name of their constant data files and store these files in the database's top-level directory, <WebZ_root>/dbbuilder/dbs/dB_name. This is the recommended location, but is not required. See constant.xml File for DC Databases for more information about the structure and contents of a constant data file. Defining Constant Data for DC or MARC Databases Refer to the following procedures for adding or removing constant data values for DC (DC(2) or DCQ) or MARC Catalog databases:
Defining Multiple Constant Data Files per Database You can define multiple sets of constant values for a local database by placing each set of constant data values in a different file and associating each constant data file with a different workform. For a database based on the DC(2) or DCQ database frameworks, define separate workforms in the database's configuration file for each set of constant data values, but use the same template (template.xml) for each workform. Each workform has its own constant data file. The database configuration files shipped with SiteSearch 4.1.2 for these database frameworks demonstrate the use of multiple workforms, each with its own unique set of constant data values. For a MARC Catalog database, which already uses multiple workforms, use a separate constant data file for each workform. Adding Constant Data to a Record There are two ways to add constant data to a record: automatically or manually. With automatic application, the constant data values appear on the data entry workform (Edit Record screen) as soon as a metadata specialist creates a new blank record. With manual application, the constant data values appear on the Edit Record screen only after the metadata specialist selects Apply constant data from the Available actions list. In both cases, the metadata specialist can edit or remove the constant data values displayed on the Edit Record screen. The database frameworks shipped with SiteSearch 4.1.2 demonstrate each of these uses of constant data. See Also constant.xml
