Library Transaction Ontology
type: Ontology
version IRI: https://w3id.org/lto/1.0
license: https://creativecommons.org/licenses/by/4.0/
Coverage: This specification presents LTO as a formal ontology to represent and process library transaction data, including circulation, interlibrary loans, hold reservations, and fiscal transactions. It promotes FAIR data and supports automated reasoning, meaningful inferences, and informed decision-making in library activities. LTO enables libraries to manage resources more effectively through collection development, respond to patron queries about item availability and location, improve resource access and exchange across networked (or branch) libraries through interlibrary loan, analyze circulation patterns to better understand user needs and demands, and others. Future work will extend LTO to other library housekeeping operations, such as acquisition and serials management.

description: A FAIR-compliant metadata vocabulary (MV), the Library Transaction Ontology (LTO), is designed and developed for representing and managing library transaction data (LTD), including circulation, interlibrary loan, hold requests, and fiscal information. Our investigation revealed that despite significant focus on bibliographic and authority data, no standardized vocabulary exists for LTD, resulting in data loss, mapping errors, and interoperability challenges during system migration and integration. LTO supports machine processing and automated reasoning for data-driven decision making. Additionally, it supports interoperability across heterogeneous library platforms by providing mappings for the circulation metadata of multiple Library Management Systems (LMS), including Koha, Virtua, Evergreen, SOUL, etc. It is also compliant with the Library of Congress's (LOC) BIBFRAME model and extends the bibliographic Linked Data (LD) framework to support the standardized representation of library transaction LD. LTO’s elements were validated through expert evaluation by LIS professionals, and its effectiveness in information processing and retrieval was successfully assessed.

Competency question: Sample competency questions (CQs): I. Find out the most frequently circulated books to support collection development. II. Check out the complete history of library circulation transactions. III. Identify patrons’ preferred mode for transactions of library resources. IV. Find out which subject area has the highest ILL demand. V. Get information on transaction details and patron involved. VI. Identify the most frequently recalled item within a discipline to add more copies. VII. Find all the transaction items of a selected library location. VIII. Get details on the ILL request initiated by a library. IX. Check out the workload distribution among the library staff. X. Identify which items have the highest renewal rates. XI. Get the average ILL turnaround time. XII. Examine how item lending policies influence the circulation of resources. This list of CQs is not exhaustive. A total of 60 CQs were formulated to check the effectiveness of the developed LTO. The full list of CQs can be accessed through the following link: https://figshare.com/s/f4a6732b6467a722b1a0.
