CSDS – Exploring Semantic Web Collections

Introduction

The Semantic Web focuses on producing a Web of linked data. The technologies used in the Semantic Web enables people to produce vocabularies and define specific rules of how such vocabularies are meant to be used. These rules will then help the computer produce inferences of how such data is linked, thus producing more accurate datasets. A growing number of Cultural Heritage organisations are now the new standards of linked data as the main infrastructure to support their collections. There is a wide range of data models or vocabularies such as CIDOC CRM, Dublin Core and Europeana Data Model (EDM). In this workshop we will focus on exploring collections under the Europeana repository and the EDM. Europeana currently holds billions of records from over 4,000 heritage organisations such as galleries, libraries, archives and museums (GLAM) among others. There are many challenges of how such collections are meant to be explored, such as the use of SPARQL querying languages. This workshop will introduce participants to the Semantic Web, and how to query such Linked Data collections. Finally, this session will use Europeana’s API to produce query interfaces to explore those collections, using the data model and producing some visualisations.

Requirements

Most of the work we will produce uses Open Source tools, and it does not require much computer resources.

To test some API calls you can download Postman.

https://www.getpostman.com/

We will be working with data from Europeana. Make sure you register for an API Key here:

https://pro.europeana.eu/get-api

You will need to work with some HTML, CSS and JavaScript (JQuery), therefore a nice scripting/programming text editor can be handy. On MacOSX, I use TextMate (https://macromates.com/), for Windows or Linux many people use SublimeText (https://www.sublimetext.com/).

Finally, we are going to build some quick Tangible queries using ReactiVision (http://reactivision.sourceforge.net/), you will need a webcam for this. If your computer already has one, that will work fine. Otherwise, any USB webcam will work fine as well. ReactiVision also provides an emulator that we can also use to prototype interfaces. Finally, we are going to be testing some of these tools on the Web in a non-standard way. For the sake of the experiment, you will need to install a legacy version of Firefox. This is because Firefox has currently disabled the option of installing plugins, that enables us to connect to ReactiVision. Please go to https://ftp.mozilla.org/pub/firefox/releases/ and scroll down to Dir 48.0.1 (Firefox 48) and install that version on your Mac or PC computer. Finally, make sure you can have access to the Web on the computer you are going to use.
