Putting the pieces togetherthe agile way
Connecting the dots in a world of distributed systems
• All the information to answer even complex questions is usually available
• But: the information is scattered across different sources and not connected yet
• Thus users/employees usually need a lot of time to connect the dots if it comes to rather complex tasks
• We think that linked data is a proper approach to solve this common problem in a world of distributed systems

Linked Data: Graph-based data model based on open standards
• Which kind of knowledge about certain things is relevant or not? Most often this can´t be described at the beginning of a project.
• Linked Data is the agile way to handle data from different sources to serve various mind-sets & complex tasks.

Integration on data level
Application on top of explicit conceptual model
What is Linked Data?
1. Linked Data is most of all a data integration technology
– Data is not necessarily stored as RDF
2. Linked Data technologies support data integration especially in dynamic & distributed environments
– Large enterprises
– Inter-Government organisations & NGOs
– WWW
3. Linked Data (Semantic Web) technologies make conceptual models behind the data visible and explicit

3 flavours of linked data integration
2. Use Linked Datafrom the web 3. Publish Linked Open

1. Make use of Linked Data principles internally

Create Linked Data -Some technologies I‘d like to mention
• from databases: D2RQ, triplify, Virtuoso RDF Views, …
• from spreadsheets, XML etc.: Google Refine, …
• from HTML/microdata/RDFa: any23, …
• from (unstructured) text: PoolParty Extractor, DBpedia Spotlight, …
• by hand: PoolParty Thesaurus Manager, OntoWiki, …

Interlink: Linked Data Alignment
• SILK: tool for discovering relationships between data items within different Linked Data sources
• LIMES: a link discovery framework for the Web of Data.
• LASSO: lookup service which helps to augment already existing, formalized knowledge with facts from the Linked Open Data (LOD) cloud
© Semantic Web Company – http://www.semantic-web.at/ 34
Searching for and querying over Linked Data
• Sindice: Billion pieces of reusable information can already be found across hundreds of millions web pages which embed RDF and Microformats. Start consuming this data today with Sindice Data Web services. http://sindice.com/
• LOD Lookup powered by Virtuoso: Lookup and search over the LOD cloud. http://lod.openlinksw.com/
• Linked Life Data powered by OWLIM: LinkedLifeData is a platform for semantic data integration trough RDF warehousing and efficient reasoning that helps to resolve conflicts in the data. http://linkedlifedata.com/

Conclusion – What can Linked Data do for you?
1. make the meaning of data and information more explicit, visible and linkable
2. data integration from different sources in dynamic environments, incl. the WWW
3. generate search functionalities and reports on top of integrated data in a cost efficient way
4. use the web and web technologies to publish data and/or metadata to leverage the value of your assets
