A Provenance-Aware Linked Data Application for Trip Management and Organization, presented at the Triplification Challenge, I-Semantics 2011. We present, an application for exploiting, managing and organizing Linked Data in the domain of news and blogs about travelling. El Viajero makes use of several heterogeneous datasets to help users to plan future trips, and relies on the Open Provenance Model for modelling the provenance information of the resources.

• Scenario in the context of tourism and travelling where the content is
Scenario in the context of tourism and travelling, where the content is
aggregated from different platforms, such as “Suplemento El País”, ”Guías
Aguilar”, “Canal Viajar” o “Prisa Digital”.
• Heterogeneous content (images, travel guides, posts, videos, news) with
different sources and from people with different profiles (journalists, bloggers
and normal users)

5. Introduction – Provenance
• Users want to know where does the information come from, who has
manipulated it and which references have been used.
•PProvenance information is critical to determine whether a resource can be
i f i i ii l d i h h b
trusted or not.
• “Provenance of a resource is a record that describes entities and processes
Provenance of a resource is a record that describes entities and processes
involved in producing and delivering or otherwise influencing that resource”
(W3C Provenance Incubator Group).
• Open Provenance Model.
• Popular provenance model centered in the evolution of the resources.
• Close to PIL (Provenance Interchange Language), currently being developed
in the W3C.

• OPM (1):
– Centered in the description of
the evolution of the resource.
• OPM profile (2):
– OPM Extension to our specific
domain.
SIOC MPEG 7
MPEG‐7 GEO 3 • SIOC (3):
( )
– Describes the social
relationships in the platforms,
OPM extension to our domain 2 plus posts and blogs.
• MPEG 7 (3):
MPEG‐7 (3):
OPM Core 1 – Image and video description.
• GEO (3):
– Localization of the resources.
