Quality control
- Creighton Barrett
Introduction
Data entered into the Archives Catalogue is stored in a MySQL database that is indexed by an open-source search engine called ElasticSearch.
Users can construct "expert" search queries to search specific fields in the ElasticSearch index and implement other search parameters not directly available via the basic search box or advanced search form.
Editors and contributors can use ElasticSearch queries to support quality control activities. For example, ElasticSearch queries can check for the existence of mandatory data elements, such as name of repository, title, physical description, authorized form of name, etc.
Editors and contributors can use search results as a "checklist" of records with specific errors or omissions to be corrected.Â
This section of the AtoM User Manual outlines ElasticSearch queries that can support quality control, data migration, bulk updates, and other activities.
