The Standard Cumulus API is based on the support of AppleEvent on the Mac OS and OLE Automation in Windows. In general, all of the functions and con- tent of Cumulus (collections, records, etc.) can be accessed by means of these two technologies. By default, Cumulus Clients feature a number of automation applications that use the Standard Cumulus API. Since the automation needed in a given organization varies, these applications are included not only so you can use them, but to give you some ideas about how you can apply Cumulus automation to your workflow. In most cases, the source is included, so you can change it to adapt to your local processes.

For more information on the applications included with each Cumulus Client, please see the Client User Guide.

The examples included with Cumulus are either assigned to certain menus by default or stored in the Additional Functions folder (subfolder of the Menu Commands folder). Three of following described examples are stored in the Additional Functions folder. You can easily assign them to a menu by copying (or moving) the example to the folder of the menu (subfolders of Menu Commands folder). Two of the following examples of the Standard Cumulus API give you a quick way to configure a cat- alog’s properties to favor performance over data security, and vice versa.

Prepare To Write IPTC

If you want to write back IPTC data to assets, your Cataloging Options (entry for the IPTC filter acti- vated) and the catalog managing these assets must be prepared for this feature. IPTC record fields have to be added and their properties have to be enabled for field linking, also Writing Metadata to Asset must be activated in the General Catalog Properties. The script Prepare To Write IPTC makes the process of preparation easy. This script prepares the Cataloging Options of the user (who started the script) to be able to write IPTC data back to assets. For Single User and administrators of the Workgroup and Enterprise Edi- tion it also prepares the current catalog.

1. Select Special (default) => Prepare To Write IPTC. A dialog box opens.

2. Select the options you want and click OK.

NOTE: ’Silently!’ if necessary

This is only necessary when Never was previ-

ODBC support ensures that any legacy database systems you already have are not lost investments. The Cumulus ODBC Connector makes it possible to choose the database that best suits your needs for storing Cumulus metadata.

Canto provides installer programs that make it easy to install Cumulus ODBC Connector. The ODBC Connector is installed as a supplementary module to an existing Cumulus Server installation on Windows.

This chapter describes how to install and use Cumulus ODBC Connector.
