A controlled vocabulary for local government and community resources categorised in a hierarchical structure under headings familiar to citizens. More details about LGCL are published in the Guidance Notes at www.esd.org.uk/LGCLGuidanceNotes.pdf.
The latest version of LGCL and its resources are published free of charge at www.esd.org.uk/standards/lgcl and other LAWs IA&S resources accessed from the esd-toolkit Web site, page: www.esd-toolkit.org/laws.
LGCL is designed to meet these objectives:
LGCL is a set of terms (of single or multiple words) in a hierarchical (or inverted 'tree') structure. Each branch of the tree may be viewed as representing a 'concept'. For that concept one 'preferred' term is given and multiple 'equivalent' terms may be given. As one drills down the inverted tree structure, terms become more specific.
With respect to LGCL it means that one term can appear more than once in different parts of the categorisation hierarchy. Wherever a term appears, it always has the same meaning.
Each term in LGCL is called an 'Item' because the list inherits a basic format common to it and other lists controlled through esd-toolkit.
The following information is stored for each item (in all controlled lists):
Additionally the following information is held for each LGCL item:
At all levels, LGCL provides one 'preferred' term and any number of 'non-preferred terms'. Non-preferred terms are classified by type, including:
Non-preferred terms allow different terminologies to be used in citizen interfaces whilst allowing all terminologies to be referenced against a common vocabulary.
Local authorities will be able to select which term they prefer to use, thereby switching between preferred and equivalent terms for local purposes.
LGCL is published in XML, Adobe Acrobat PDF, Microsoft Word, CSV spreadsheet and RDFS formats. It is also issued in an XML format that matches the format used by the old APLAWS Category List. Transformations to other formats will be published where there is sufficient demand.
Mappings between LGCL and other controlled lists are published in XML, Adobe Acrobat PDF, Microsoft Word and CSV spreadsheet formats.
Yes, it can be used as a default structure, where none exists.
The LGCL hierarchy may be seen as a categorisation of resources commonly found on local government Web sites sub-divided in a way that might allow a content author to locate an item of metadata.
By mapping the terms in LGCL to a structure which matches your navigation requirements. esd-toolkit is being modified to allow subscribing authorities to restructure the hierarchy and output it in the standard LGCL format.
Because LGCL provides an even spread of categories across subject headings. Top level terms are broad. As you go lower down the hierarchy, terms become more specific. The categorisation structure may be seen as a useful starting point for a Web site navigation hierarchy, but councils will normally change this hierarchy to match their citizens' navigation requirements.
Submit them for consideration as part of LGCL in one of these ways:
LAWs has produced guidelines for applying metadata to Local Authorities Web sites at http://www.esd.org.uk/LAWsMetadataGuidelines.pdf. These build on the Office of the e-Envoy's electronic Government Metadata (eGMS) guidelines published at http://www.govtalk.gov.uk/schemasstandards/metadata.asp. eGMS provides elements (types of information, such as 'creator' and 'subject') and element refinements which contain values describing resources, such as Web pages.
Guidelines recommend, and LAWs data schemas mandate, that certain metadata elements be populated from controlled lists.
LGCL provides a controlled list for populating the 'subject' metadata element. Two subject refinements are relevant:
Underlying metadata should always use the preferred term, although portals and search engines may need to allow for metadata using terms that are no longer preferred, but were in a previous version of LGCL.
Whenever LGCL is used to populate metadata elements, 'LGCL' should always be explicitly referenced. For HTML Web pages, reference is made via the 'scheme' attribute of the 'meta' tag. Further guidance on metadata in LGCL is available in www.esd.org.uk/LGCLGuidanceNotes.pdf.
Yes. There are mappings from every PID List (aka the Local Government Service List) service to a single LGCL category. It is published in XML, Adobe Acrobat PDF, Microsoft Word and CSV spreadsheet formats. Links for all the formats are in this diagram: http://www.esd.org.uk/standards/lgcl/lgclresourcediagram.html.
Yes. There are mappings from every ACL term to a single LGCL category. It is published in XML, Adobe Acrobat PDF, Microsoft Word and CSV spreadsheet formats. Links for all the formats are in this diagram: http://www.esd.org.uk/standards/lgcl/lgclresourcediagram.html.
No, from 1.01 onwards, terms will never be deleted. Terms may be 'deprecated' by being changed from 'preferred' to 'non-preferred'.
Yes, if appropriate, terms may be moved across the hierarchy in updates.
LGCL identifies shortcuts for a small number of terms. These terms are recommended by LAWs for adoption as common shortcuts across local authority Web sites.
Shortcuts are added to the Web site address of a local authority to provide a URL for a Web page with corresponding subject matter. For example: www.mycouncil.gov.uk/recycling should go to a page with content on rubbish, waste and recycling. In addition to national shortcuts related to LGCL terms, authorities may publish and support their own local shortcuts.
The final section of the Word document www.esd.org.uk/standards/lgcl/lgcl.doc shows the shortcuts together (in human readable form).
LGCL is split into separate XML files which are brought together in the lgcl.xml through transformation. These files are as follows:
The split of XML files is done to allow component parts to be combined in different ways for different purposes, whilst still using one standard list of terms.
To accommodate more information. Also LGCL is published in a format suitable for other controlled Lists to be maintained through esd-toolkit. For legacy systems, LGCL is also published in ACL format.
