1. Tallinn, 13 December 2005 Syndication Adriana Baciu Finsiel Romania

2. 2 Collaboration  Collaboration = give + take = export + import (information)  XML – define the concept (DTD, Schema) and then describe your structure  Schemas: RSS, RDF (Dublin Core), Darwin Core  DC metadata such us Author, Contributor, Release date, Source of information  Resource Description Framework (RDF) is a framework for representing information on the Web, A “machine readable web page”  XML/RPC, SOAP – making (complex) objects travel, used in searches

3. 3  Fast content for web sites with RDF  Spot the orange button  The information is not “took over” by the hosts websites, but instead “advertised” on those  The RDF channels are automatically updated on regular basis (can be parametrized using the specific OS scheduler), without further requirements of human resources Always fresh

4. 4 EC CHM 2 syndication  Local channels:  Default channels:  News, Stories, Events (exporting latest or selected list of items), not editable.  News channel  Custom channels, later defined by administrators for specific types of information  Every section has a channel  Remote channels:  RDF channels exposed by other sites that the portal harvests  Administrators control the list of harvested channels  Harvested information is displayed with the use of portlet

5. 5 Administering the syndication

6. 6 Display the syndicated information  Portlets are the tool for display:  Create a portlet for every new remote RDF channel you insert in your portal and display it where necessary;  Default local channels (latest or selected list of items), each has an associated portlet  “Local Channels” is a special portlet that displays the list of your local channels (makes your syndicated information easy to be retrieved by visitors)

7. 7 Portals in your network  Usage of XML/RPC techniques, remote search launched from local portal.  Allows the creation of a list of portals that are able to respond to free text searches, “Other Searches” section of your portal.

8. 8 EC CHM net registry  Central place for the registration of existing RDF channels in the CHM sites and collaborators network  Central place for retrieving the locations of such channels  The EC CHM site administrators can register/retrieve information about existing collaboration  Registered RDF channels are divided into categories by the type of items they contain (News, Red Lists, Miscellaneous)  Sites/portals built using the EC CHM 2 technology just declare their existence, the list of channels is automatically discovered

9. 9 EC CHM net registry  Used also to declare the participation into the CHM network of portals.  Portals automatically searched in advanced searches from various sites using XML-RPC (EC CHM v2 software allows that)

10. 10 How it functions

11. 11 What’s needed for RDF  Local tool for collecting information and export in RDF format  Local tool for RDF harvesting and interpretation into human readable format  Support for XML-RPC if external searches are to be performed over the local site  RDF channels are automatically generated and can serve anybody at anytime
