Hello again CSpace Colleagues, In order to facilitate data migration for several UCB deployments, work has commenced on an initial version of the concept authority structure to be included in CSpace ver. 2.3. This initial version (see http://wiki.collectionspace.org/display/deploy/Concept+Authority+Requirements+-+UCB) will be basic, with support for one term per record, as is now the case in Person, Org, and Storage Location. Singular and plural word forms (e.g. "painting" and "paintings") will need to be added as separate term records, as will their equivalents in other languages (e.g. "peinture", "peintures", "pintura", "pinturas", etc.). Hierarchical relationships between broader and narrower terms will be supported. A more robust version of the concept authority, planned for ver. 2.4, will provide support for the use of both preferred and non-preferred terms, and support for multilingual deployments by the introduction of a repeatable term block with the following fields: displayName shortDisplayName source sourcePage termLanguage preferred preferredForLang historicFlag termType qualifier In this model, singular, plural, and variant descriptors in other languages will all reside in a repeatable term block within a single concept authority record, making the selection of any of these term forms for use within a single record possible without creating separate records for each. More details about the refactoring of authorities to support this new model in 2.4 will be shared with the talk list soon. Jan Eklund
