2. WP3: Micro services for small and medium
institutions

environment for tools and services

participative testing and validation of each of the
services and applications

5. What is a Web Service?
A web service is a software function provided at a
network address over the web or the cloud (24/7)
• are application components
• communicate using open protocols
• are self-contained and self-describing

that are taken over
into the application.

9. Task 3.4: Vocabularies and languages
• Experimental application to enable local cultural
institutions to collaborate in the development of
multilingual vocabularies for local history and
archaeology
2 Vocabularies

10. The application will be based on:
ISO 25964: standard for building thesauri
• Part 1: Thesauri for information retrieval
- published in 2011
- developing a thesaurus (mono- and
multilingual)
- replaced previous standards ISO 2788/5964
- includes data model and XML schema
• Part 2: Interoperability with other vocabularies
- published in 2013
- recommendations for the establishment and maintenance of
mappings between multiple thesauri, or between thesauri and
other types of vocabularies
2 Vocabularies

11. The application will use SKOS as exchange
format:
SKOS Simple Knowledge Organisation System
• is a W3C recommendation designed for
representation of controlled vocabularies
• main objective is to enable easy publication and use
of such vocabularies as linked data
2 Vocabularies

12. How this two relate…
• The SKOS metamodel is broadly compatible with the
data model of ISO 25964-1 - Thesauri for Information
Retrieval.
• ISO 25964-1 advises on the selection and fitting together
of concepts, terms and relationships to make a good
thesaurus
• SKOS addresses the next step - porting the thesaurus to
the Web.
2 Vocabularies

13. Using SKOS, concepts can be identified using URIs,
labeled with lexical strings in one or more natural
languages…
The SKOS Core Vocabulary is an application of the
Resource Description Framework (RDF), that can be
used to express a concept scheme as an RDF graph.
Using RDF allows data to be linked to and/or merged
with other data, enabling data sources to be
distributed across the web, but still be meaningfully
composed and integrated.

22. Vocabulary Management – Business Process/Workflow
The process of editing and
managing a vocabulary
involves the communication
between different persons
and the technical system:
Eg. Finding a term,
Requesting a candidate term,
Accepting the new term,
Updating the vocabulary etc.
User uses web
service for finding a
vocabulary term
Term exists in the vocabulary
SaaS
Crowdsourcing
Term does not
exist in the
vocabulary
Use
crowdsourcing
for finding a new
candidate term
3 Voc. Tool

23. Outcomes of Copenhagen - WS1
Access to the vocabulary:
• Online access point (see TGN example)
• Integration into local application (see Genre example)
Import of existing vocabularies into the LoCloud experimental vocabulary
application (pre-requisite: skosified, multilingual, open access)
• Subject vocabularies
• Object Types
• Geographic Names
• Suggested vocabularies: UNESCO Thesaurus, UKAT
(http://www.heritagedata.org/blog/vocabularies-provided/ ? UK)

24. Outcomes of Copenhagen
General usage of the tool
• Everybody allowed to enter new terms vs. Suggest candidate terms
• Multilinguality: language translations assigned to partners
Other wishes?
• Crowdsourcing?
• Automated Vocabulary enrichment
