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

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

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

Administering the syndication

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

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

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

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)

How it functions

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
