The Language of Bindings Thesaurus (LoB) includes terms which can be used to describe historical binding structures. The thesaurus can be used as a lookup resource through this website and also as a software service where the terms can be retrieved directly through your own application. LoB is a young project and community contribution will ensure that it will be improved.
How to contribute
If you wish to contribute to the project you need a named account on this website. You can get one by sending us a message over here. After you receive your account details you will be able to log in and:
- suggest new terms that are currently not on the thesaurus
- suggest changes to existing terms by commenting inside each concept page
Read more about current and past contributors to the LoB over here.
LoB is based on SKOS
The thesaurus is structured based on the Simple Knowledge Organisation System (SKOS). Some of the main principle of that system are:
- We define concepts (not words) to avoid common problems such as when different communities use different words for the same idea.
- Each concept can have a number of labels (language words) which refer to the concept, with one of them being a recommended label (preferred label) and the rest being the alternative labels.
- Concepts are organised from the more general ones, the broader concepts, to the more specific ones, the narrower (broader / narrower relationship). A narrower term should always describe a concept which is included in the parent concept. For example, adzes is a narrower concept of tools and equipment because all adzes are tools.
You can access LoB concepts using three tools on the website:
- The search page where you can type a keyword and retrieve relevant results.
- The alphabetical page where the concepts are organised alphabetically by preferred label.
- The hierachical page where the concepts are grouped based on their broader / narrower relationship.
LoB concepts are described in the so-called scope notes, which aim to give both a brief definition of each concept as well as a broader indication of what the concept is about, together with some historical information where this is known and relevant.
Getty Arts and Architecture Thesaurus
Where possible we have matched our concepts with concepts from the Getty AAT. Our intention is to submit LoB concepts to the AAT where corresponding terms do not exist.
The thesaurus is meant to be used as part of a documentation system. We recognise the value of the CIDOC-CRM in the documentation of cultural heritage. For this reason we have chosen our top concepts to match CIDOC-CRM entities so that their narrower concept hierarchies can be used as E55 Type for these entities in a documentation system. However, using a CRM compatible documentation system is not required.
To avoid link rot each concept has a so-called persistent URI provided by w3id.org which currently redirects to the corresponding concepts in the Language of Bindings website hosted under the Ligatus domain name. This means that in the future the LoB website can move to another domain without affecting any records produced based on these links. The redirection is with code 303 as recommended here.
LoB as a service
Similar links also exist on each concept page. This is the recommended way to retrieve data for applications from the thesaurus.
The LoB website also offers a legacy lookup service (with less complete records) through these links:
- For a JSON representation: http://www.ligatus.org.uk/lob/api/views/search_service.json
- For an XML representation: http://www.ligatus.org.uk/lob/api/views/search_service.xml
The parameters passed to these pages can be:
- key can be used to pass any string as a search term
- filter is useful when you want to limit the results to the narrower concepts of a given concept. filter accepts the id of the parent concept. For example for http://www.ligatus.org.uk/lob/concept/2893 the id would be 2893.
- uri can be used to retrieve terms for which the uri is known. For example http://w3id.org/lob/concept/2893
- To search for terms containing hinge, one would try this link:
- To search for any child concept of bookmarks (id: 2837) which contains marker in the preferred label, one would try this:
