The Information Workbench as a Self-Service Platform for Linked Data ApplicationsCOLD Workshop @ ISWC, Nov 23, 2011

Peter Haase, Michael Schmidt, Andreas Schwartefluid Operations AG

Linked Data Application Development is a Difficult Task

Example: Linked Data-ThonBuild an end user oriented Linked Data Application in two weeks, using ISWC metadata and other Linked Data sources

Challenges

• Discovery and automated integration of relevant data sources

• Heterogeneity in various dimensions

• Quality of Linked Data

• End-user oriented interfaces

Platform for Linked Data Applications

Information Workbench: Semantics- & Linked Data-based

integration of private and public data sources

Intelligent Data Access and Analytics

Visual Exploration Semantic Search Dashboarding and Reporting

Collaboration and knowledge management platform

Wiki-based curation & authoring of data

Collaborative workflowsSemantic Web Data

Self-Service Application Development Process

1. Provisioning of the Software Platform• Delivered through a Self-Service Portal• Hosting in public or private clouds

2. Linked Open Data Discovery• Access to data registered at global registries,

e.g. ckan.org, data.gov, …• Visually explore data sets and

identify those relevant for your application

3. Data Integration• Integrate the data sets with the click of your mouse• Add providers for internal and external legacy data

4. Customization of the Frontend• Semantic Wiki + Widgets as Self-service Linked Data Frontend• Declaratively customize the user interface using a selection of widgets

5. Extending the Platform with own Components• Use APIs and SDKs to implement your own widgets, providers, etc.

Advanced configuration

Semantic Wiki + Widgets as Self-serviceLinked Data Frontend• Semantic Wiki for collaborative authoring and linking of

unstructured and structured semantic data• Declarative specification of the UI based on available pool of

widgets and simple wiki-based syntax• Widgets have direct access to the database• Embed dynamic data, visualizations, forms, etc.• Type-based template mechanism
