Metadata management of the third generation library service platform: A
case study of FOLIO codex
〇a*
XU Lei & XIA Cuijuan〇
In the era of digitalized network, user needs and the forms of library services have developed
towards the direction of specialized knowledge and smartness. Facing this new norm, the
metadata management of the third generation library service platform not only needs to solve
the present situation of the library integrated management system or even the next generation
library service platform beset by MARC to meet the requirements of integrated resource
management and business integration, but also considers a unified method of data modeling
and coding to achieve cross-typed data stream and knowledge organization and fusion. This
poses new requirements for metadata management, including: complete life circle management,
compatibility of resource types and standard specification, bibliographic control and authority
control, and knowledge organization and fusion. The possibility of using platform thinking to
change the ecology of library operation shows promise in the FOLIO project. As a library service
platform based on micro service architecture, FOLIO at the start of its design has defined a
core micro domain—Codex. On the one hand, as the data registry center and data intermediary,
Codex is positioned at the top of the FOLIO architecture and can remove differences in encoding
and format in different domains and span storage location to reduce the data exchange and
system coupling between different domains. On the other hand, based on the BIBFRAME 2
model, Codex designs an abstract data model “Work-Instance-Item” and a set of minimum
core metadata elements by drawing from the DC elements. Codex does not describe the detailed
information of resources and only play a navigating and positioning role. Exclusive business
information or more detailed records can be assessed by getting to the recording level through
Codex. As the core metadata management domain, Codex will be designed as the FOLIO
platform’s resource link center, authority data center and entry point for resource management,
and establish relationships between resources through the abstract entities in the model. Although
currently only the Codex Search, which does not store its own data, is realized and the support
for linked data still needs to be improved, Codex is flexible enough to support the descriptions
and organization of entities, whether it is the abstract data model, or the minimized metadata
proposal, or the hierarchical description principle of formal records—working records—unifying
records.
