Background
The London Museum
had a requirement to better manage its collections and non-collections digital assets. These had been managed in different systems which were not integrated, resulting in duplication of effort and data about the same asset which was not synchronised. Any solution would need to integrate with its collections management system (CMS), the system of record for descriptive and contextual information about its extensive object collections.
The museum decided to procure Portfolio DAMS from Extensis, who worked in partnership with Knowledge Integration - who provide middleware that can act as broker between different information systems, enabling seamless transfer of data.
Alex Bromley Consulting was commissioned to project manage the integration between the three systems.
The work
The first act was to draw up a document outlining the principles upon which the integration would work. This was a vital first step to ensure all parties knew the scope of work. Issues included in the Data Management Policy were:
- Number and type of records to be shared between the three systems.
- Which application was the system of record for which data type.
- Initial scope of integration between the three systems, i.e. direction and frequency of ingest/sharing.
- What of the various file types were to be ingested by the DAMS.
- The metadata that would provide the link between the three systems.
- Nature and extent of data transformation required.
- Statement on potential use of taxonomies.
The DAMS team at the museum developed a metadata schema for Portfolio, covering their requirements for both collections and non-collections assets. There also needed to be a field in the CMS to act as a ‘flag’ to indicate whether a record was ‘DAMS Ready’.
Using this as the basis, a mapping was made between their schema and that of the collections management system, taking into account field type and definitions. This was given to Knowledge Integration who used the CIIM to pull the relevant fields of the chosen records at a set frequency, then push them into Portfolio. User permissions in Portfolio enforced data integrity, ensuring this information was not edited by users of the DAMS.
After consultation with Knowledge Integration, a decision was made on the common element between the two data sets that would act as the ‘join’. In this case it was the asset file name and path (the museum had a mixture of filenaming conventions developed over the last twenty years so using the filename alone would not have worked).
A vital piece of information that DAMS users would require was copyright and credit line information about collections images, currently stored in the CMS. Rights data in the collections management system had been partially cleaned after an upgrade to the application in 2016 and any rules had to take into account the differing levels of quality and detail of rights data available. Where data had been cleaned a detailed series of check boxes indicated what were the permitted uses.
As a baseline, it was agreed that any rights data that had not been ‘cleaned’ in the home system would not be pulled into DAMS and users were directed to seek help from the Picture Library. Where data had been cleaned (which had been conveniently flagged in a check box) then I developed transformation rules which took the permitted uses (stored in a Y/N check box) and turned them into a bulleted list of permitted uses, topped and tailed with user friendly text.
Knowledge Integration utilised their Collections Information Integration Middleware (or CIIM) to do this transformation and push from collections management system to Portfolio.
Outcomes
The project achieved a minimum viable product for the museum, enabling them for the first time to utilise a digital asset management system which shared data with another application containing related information. Users of the DAMS are now able to search both collections and non-collections images, view descriptive and contextual metadata, as well as vitally important rights data outlining permitted uses.
For the moment, the museum will use a manual system for moving images from the network and placing them into Portfolio, based on the existing set of 90,000 object records and associated images which has been published online. Digitisation procedures for collections and non-collections images continue to utilise different approaches but over time these will be integrated into Portfolio, with that application serving as the system of record for all digital assets in the museum. In this future scenario, the CIIM would synchronise data two ways - CMS data to the DAMS, and media and media metadata from DAMS to CMS.
