Content-based dataset search with Spinque PSSA

Posted on by in Search Application using ODN, Spinque | Leave a comment

Within the COMSODE project Spinque applied its Search by Strategy approach to Open Data. We successfully extended the approach to Linked Open Data and we demonstrated the technology through several search applications. At the end of the project we are very pleased with the result and we are grateful that we got the chance to help the Open Data community a bit forward within the Comsode project. 

We still wanted to do one more thing; during the project an additional request for search functionality came up. Can we use Spinque to find datasets? Although not anticipated in the project proposal we wanted to support this. Spinque’s Search by Strategy approach is, however, not the best match for this purpose. This type of search functionality asks for Spinque PSSA. Let me explain…

Publishing culture data

This blog post is the third and final part in a series of posts on creating advanced search applications with Spinque and the Open Data Node. We go to the beginning of the chain and describe the transformation and publication of the datasets itself. Using the Open Data Node we transformed, integrated and published five datasets.

Linked Open Images

Posted on by in Activities, Search Application using ODN, Spinque | Leave a comment

In a previous blog post, we introduced CultuurLINK as a service for the cultural heritage community to integrate collections by linking their controlled vocabularies. As an example we showed how to connect the internal subject term list from the NIOD Institute for War, Holocaust and Genocide Studies with a large audio visual thesaurus (GTAA) from the Netherlands Institute for Sound and Vision.

Today, we put these newly created links into action. Linked Open Images is a mobile application to explore historic material about World War II that gives access to three Open Data collections: historic (1) Dutch news reels shared by Sound and Vision and (2) Photographs and (3) Books shared by NIOD.

Linking data sources with Spinque

Posted on by in Press Release, Search Application using ODN | Leave a comment

An important part of the COMSODE methodology is to make datasets available in an integrated fashion. One aspect of this integration is the alignment of datasets by linking entities from one dataset with the same entities from another dataset. In this blog post, we describe how we applied Spinque’s Search by Strategy approach to linking vocabularies in the cultural heritage domain.

Many heritage institutions describe their objects using terms from predefined vocabularies. Linking these vocabularies aids the integration of the collections. Hereto, The Netherlands Institute for Sound & Vision and Spinque teamed up to develop CultuurLINK. With CultuurLINK owners of a digital heritage collection can link their (internal) vocabularies to the Dutch cultural heritage hub. The hub contains several large vocabularies that are core for the community, such as the audiovisual thesaurus provided by the Netherlands Institute for Sound & Vision. Links to the vocabularies in the Hub enable richer descriptions for the collections, for example in the form of additional background information and labels in multiple languages. And, links between vocabularies connect formerly isolated collections, enabling richer and more contextualized access.

Building an application on Open Data with Spinque

Posted on by in Press Release, Search Application using ODN | Leave a comment

In this post, we explain how we build a prototype application on top of three linked datasets. We detail how the required backend services combine information from multiple sources and how we constructed these services with Spinque. Using Spinque’s search by strategy approach, we were able to create all required backend functionality by constructing strategies in the graphical editor; not a single line of code had to be written!
