User submits video item to repository

Video filter (org.ejamaica.app.mediafilter.MPEGFilter) runs periodically creating copy of video submission in streaming format, on the media server.

WMS Server for spatial itemsWMS Server for spatial items

Users maintain collections of various spatial data documents containing bitstreams submitted as format:shape.

Periodically a cron job runs a script that creates links to the shape files in the asset store, for use by the WMS server (GeoServer).

The shape files are added to the WMS server configuration as layers.

A map file is created referencing the shape files as layers.

From the repository items, various composite collections are built reflecting the community of users.

eJamaica.org CommunityeJamaica.org Community

Users maintain collections of XML text documents submitted as type:saying.

<saying> <phrase>What is fi yu, cannot be un fi yu.</phrase> <author>Unknown</author> <meaning>If it was meant to be, it will be.</meaning></saying>

<saying> <phrase>What is fi yu, cannot be un fi yu.</phrase> <author>Unknown</author> <meaning>If it was meant to be, it will be.</meaning></saying>

Periodically a cron job runs a sayings filter that extracts all documents of type saying not yet read, and updates the sayings database.

Another cron job periodically extracts a random saying as a text file, which is included in eJamaica.org home page.

Users maintain collections of XML text documents which are submitted as type:placename.

Periodically a cron job runs a filter that extracts all documents of type placename not yet read, and updates the placenames database.

The placenames database will be available via KML format for use in various mapping application.
