(This is an initial release as part of PAM Build 40. Functionality may change subject to user feedback) Description
Creates a summary page and a CDF (Channel Definition Format) file for its incoming product. To access the CDF page remotely the following URL may be used:
http://your.pam.here:pamPort/PAMSupportDir/CDFSubscriptions/index.html
(substitute your.pam.here with the network name of the machine with PAM and substitute pamPort with the port number that PAM is serving on - typically 19090)A master CDF Subscription Page allows users to view all of the available summary pages and CDF files through a web browser. The master CDF Subscription Page shows summary pages and CDF files for all of the active putCDF DIMs. By clicking on any of the "Subscribe" links on the subscription page, the user will automatically be subscribed to that channel. Both Internet Explorer and PointCast are able to understand the CDF generated by this DIM. Note that the same CDF file is used for both Internet Explorer and PointCast. Internet Explorer ignores PointCast tags and attributes that are non-standard CDF.
This output agent (DIM) should be used in conjunction with an archive juggler so that files which the subscription page points to are not garbage collected. This allows users to subscribe to channels and view channel content even if PAM is shut down.
The schedule specified in the CDF file matches the schedule of the handler that feeds into this output agent. If the handler has no schedule or the schedule cannot be specified in CDF, then the default schedule is used. The default schedule tells clients to update channel content daily (every 24 hours) using smart-pull.
Configuration Variables
updateIntervalSecsUnits are in seconds, default of 600 (10 minutes). This determines the rate at which the master subscription page is updated.How it works
This DIM takes its input product and creates an index page of the contents. Then, it creates a CDF file which points to that index page, so that users can subscribe to the information in the DIM's product. It relies on an archive juggler to make sure that its product is not garbage collected. The schedule specified in the CDF file matches the schedule of the juggler that feeds into this putCDF DIM. Otherwise, if the juggler has no schedule or the juggler's schedule cannot be specified in CDF, then a default schedule is used in the CDF file. The default schedule tells clients to update channel content daily (every 24 hours) using smart-pull.
