Trajectory modelling of publishing costs using Open Research Information - An open source analytics pipeline

  • 1. Sesame Open Science

Description

Through a project initially supported by IReL and building from previous work undertaken by the Curtin Open Knowledge Initiative and Invest in Open Infrastructure, we have built a system for examining the costs of potential future scenarios, based on cost parameters calculated from available data. In this analysis we use the example of the Council of Australasian University Librarians (CAUL, the Australia-Aotearoa New Zealand library consortium) and Bibsam (the Swedish library consortium) to demonstrate a system that implements this analysis.

Notes

Code and data availability

The main public data used as primary sources is detailed in Table 1. All code, including SQL templates, configuration files, the python visualisation library and resulting graph images and aggregate CSV files supporting them are available at https://codeberg.org/TwoBirds/dbt-cost-model 

All intermediate tables generated by the code (including all record-level tables) are available in Google Big Query:
https://console.cloud.google.com/bigquery?ws=!1m4!1m3!3m2!1ssos-project-space!2sBibsam_2026 (Bibsam)
https://console.cloud.google.com/bigquery?ws=!1m4!1m3!3m2!1stwobirds-463608!2scaul_2026 (CAUL)

An interactive version of the trajectory modelling, including baseline values and preset parameters for the OA scenarios described in this paper, is available as Google Spreadsheet (for Bibsam):
