Use effective labels to enable IDS to determine which documents to publish based on effective and expiration dates.
The effective label specified in a content delivery configuration allows IDS to determine when to publish a particular document and when to delete it from the website. IDS does this by examining the repeating properties a_effective_label, a_effective_date, and a_expiration_date, which are properties of the dm_sysobject type. These properties are inherited by all subtypes of dm_sysobject.
Each a_effective_label corresponds to a matching a_effective_date and a_expiration_date. Because these are repeating properties, you can specify multiple effective labels, effective dates, and expiration dates for each document. IDS looks for the effective and expiration dates matching a particular effective label, and uses the dates to determine when to publish a document and when to withdraw the document from the website.
For example, a document might have the effective label, effective date, and expiration date properties set as follows:
Table 12.6. Using effective labels
| a_effective_label | a_effective_date | a_expiration_date |
|---|---|---|
DRAFT | 03/05/08 | 03/15/08 |
REVIEW | 03/16/08 | 03/26/08 |
COMMENT | 03/27/08 | 04/10/08 |
APPROVED | 04/10/08 | 04/10/09 |
Setting the document’s effective label to REVIEW means the document will be published on March 16, 2008 and removed from the website on March 26, 2008. Setting the effective label to APPROVED means the document will be published on April 10, 2008 and withdrawn on April 10, 2009.
Documents whose effective label does not match the effective label set in the content delivery configuration are published regardless of the values set for effective date and expiration date.
