Abstract

Since 2017 the Schools Catalogue Information Service (SCIS) has enabled users to search the SCIS catalogue by curriculum learning area. A rules-based algorithm is used to infer the learning area to which records are aligned. This paper explores the possibility of using machine learning to supplement or replace the current approach. Multi-label supervised classifiers were trained on topical headings from a large dataset of digital learning resources from the Scootle repository. They were then tested on a smaller set of SCIS records and demonstrated adequate results for a subset of learning areas, with better precision than recall. Methods for improving classification are discussed.

Abstract

In 2020, the Schools Catalogue Information Service (SCIS) commenced a project to replace its existing cataloguing system with Koha, an open-source library management system. Catalyst was appointed to undertake the installation, data migration and integration with SCIS’s existing systems, as well as providing training and ongoing support. This paper describes the project-management process and how it was adapted to accommodate COVID-19 lockdowns. It outlines customisations and additional developments undertaken to support SCIS’s specific needs and workflows, and further work and on-going support arrangements in the post-launch phase.

Abstract

Until 2017 the Schools Catalogue Information Service (SCIS) used the library industry standards MARC-21 and z39.50 to transmit data to subscribers’ local school library systems. SCIS launched a new platform in July 2017 and a set of APIs in March 2018, for the first time offering alternative transmission options compliant with ubiquitous web standards. These developments enabled SCIS to add value to its data, remove impediments to access, support on-the-fly provision of metadata for online resources, and pave the way for further innovations around RDA. This paper describes the new SCIS online services and the factors driving them.

SCIS Resource Type Thesaurus: a linked data vocabulary for inferring Resource Type from MARC records

Abstract

Resource Type (RT) is a multifaceted concept that is encoded in a range of elements in Machine-Readable Cataloging (MARC) records. However, expressions of RT are often unhelpful to users, and many records are inconsistent in how they represent it. The Schools Catalogue Information Service (SCIS) Resource Type thesaurus (SRT) is a linked data thesaurus defining RT categories, enabling searching, limiting, sorting and faceting by RT in the SCIS online catalogue. Semantic relations within SRT enable mappings to and from the thesaurus in spite of variations across legacy and current MARC records. The purpose, design, and possible applications of SRT are discussed.

Abstract

Australian school libraries have an expressed need to organise resources according to Australian Curriculum (AC) outcomes. Education Services Australia (ESA) has aligned digital resources to the AC since 2011, publishing it on platforms including Scootle. The Schools Catalogue Information Service (SCIS) at ESA creates and distributes MARC records to 93% of Australian school libraries, but has not traditionally provided curriculum-alignment data. This paper describes a trial in which headings from a linked data subject vocabulary (the Schools Online Thesaurus) in MARC records are supplemented with URIs for the purpose of consuming AC alignment data. A widget is presented to demonstrate possible downstream applications.
