3. The Vision The eJamaica.org vision is a Jamaica where the citizens have easy access, and the means to share information of cultural, scientific, educational, and historical value.

4. The Goal eJamaica.org is a Public Digital Repository (PDR) that seeks to promote the sharing of information on Jamaica stored in electronic format by: • the provision of a long term storage space; • a framework for the sharing of the data; • tools to assist users in creating, managing, publishing and analyzing the data. The PDR will foster the development of partnerships between persons and organizations with information to share, and persons requiring information.

6. What’s Available ? • digital content storage (100MB / user); • tools to assist users in creating and managing their collections; • Blog; • additional search criteria based on spatial context of item; • peer review process to rank repository content; • a facility to encourage partnerships between data gatherers and information users for their mutual benefit; • inclusion in google web search engine via google sitemaps.

12. Collection Management Tools

13. Tools cont’d Tools will be available to assist users create specialized content and update metadata easily. • add geo-referencing metadata to items; • create CSV text files of data points for inclusion in repository; • 2D charting of CSV data files; • create interactive map files; • create xml text files for specialized content; • spatial data management tools;

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

17. WMS 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. <dspace context url>/bitstream/<dspace handle>/<item id>/<bitstream id>/<item filename> /<geoserver data path>/<dspace handle>/<item id>/<item filename>  <dspace assetstore>/<bitstream path> <datastore id=“<user email>:<item name>" enabled="true" namespace=“<user email>”> <connectionParams > <parameter name="url" value="file /<geoserver data path>/<dspace handle>/<item id>/<item filename>"/> <parameter name="namespace" value=“<user email>”/> </connectionParams> </datastore> <namespaces > <namespace prefix = “<user email>" uri="http://www.ejamaica.org/dspace/<user email>"/> </namespaces> <map> <layer> <name value=“<user email>:<item name>"/> <url value="http://www.ejamaica.org:8090/geoserver/wms"/> <visible value="true"/> <srs value="EPSG:3448"/> </layer> </map>

19. eJamaica.org Community From the repository items, various composite collections are built reflecting the community of users.

20. Community of Jamaican Sayings/Proverbs 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> 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. curl http://localhost/dspace/update-saying Updating current saying: Sat Mar 01 17:17:38 EST 2008 Handle: handle/1876/119 Saying: What is fi yu, cannot be un fi yu. Author: Unknown

21. Community of Jamaican Placenames <address> <name>Bath</name> <description></description> <street></street> <street1></street1> <postal_code></postal_code> <latitude>17.946165</latitude> <longitude>-76.354337</longitude> </address> 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.

22. Ranking Repository Content A form of Peer Review will be used to rank repository content. • repository oversight board; • rotating membership by user activity and standing in the community; • monitoring and rating repository content; • recommending repository content for inclusion in eJamaica.org preferred collections; • usage determined ranking;
