The document provides an overview of the key components and features of a data center application. It describes the integrated data model, search, and views. It also outlines how the data center allows users to define data sources, annotators, thesauri, custom views, and extendable search. Dashboards can include replaceable modules and standard gadgets. The architecture uses OSGi, VAADIN, Sesame, and JackRabbit and the roadmap includes internationalization and collaboration features.

2. What is the data center
Data integration solution
Web-based application
Modular

3. What is the data center
Integrated data model
Integrated search
Integrated view

4. Data Model
Design the data model

5. Data Model
Design the data model
OWL syntax
Open source tool Protege can be used
Dynamic upload / download in the datacenter

6. Thesauri
Define thesauri
Use SKOS Thesauri to define your glossar
automatic search term expansion
Dynamic upload / download in the datacenter

7. Data Sources
Define data sources
databases
documents
linked data on the web
user generated content

8. Data Sources
Define databases
all databases with JDBC drivers possible

9. Data annotation
Define annotators
keyword extraction
categorization
enrich data
link data

10. Data annotation
Define annotators
per default, there is a simple keyword extraction for
documents
classifier has to be trained
you may want to have custom annotators for your data

11. Data annotation
Training

12. Data annotation
Classification can be trained on the fly by drag and drop elements

13. Data annotation
Manual annotation always possible (rating, keywords, comments)

14. Data views
Define custom views
There is a default view for data
You may want to have custom views for different types of
elements
Dynamic replacement of views possible at runtime

15. Search
Semantic search
Automatic search term expansion according to the glossary
Facets and filters

16. Search
Search is extendable

17. Briefcase
Collect links to documents

18. Dashboard
Replaceable modules in the dashboard
You may want to have custom modules
Gadget compatible!

19. Dashboard

20. Dashboard
Standard gadgets can be plugged in

21. Dashboard
The Leo translator gadget

22. Monitoring
Web-based monitoring

23. Architecture
OSGi based on Apache Karaf
VAADIN ui framework
OpenRDF Sesame triple store (replacable)
Apache JackRabbit content store

24. Roadmap
Internationalization
Collaboration
