RDF Developer

Tender description

Summary of the work Develop a consolidated pan-archival RDF metadata catalogue to meet users’ needs and implementing this by building ETL processes, an RDF triple store and API services, underpinned by AWS Neptune and AWS Elasticsearch. Specialist role Developer Expected Contract Length Until 31 March 2022, with an option to extend by up to 6 more months Latest start date Monday 17 January 2022 Maximum Day Rate Up to £750 per day Early Market Engagement We ran a Discovery phase leading to plans for an Alpha using AWS Neptune and Elasticsearch. You can read more about the project: https://www.nationalarchives.gov.uk/about/our-role/plans-policies-performance-and-projects/our-plans/our-digital-cataloguing-practices/project-omega/ The Discovery produced a proposal for a new Catalogue Data Model using RDF, a new identifier scheme, and transformation routines for the existing data to the new model. We have held workshops identifying the key ways that staff managing the catalogue work with the data and what they would like in future. The archivist needs to search, analyse, add to, correct, edit, enhance record descriptions so that the catalogue is properly maintained. The archivist needs to work with catalogue entries individually or as large sets, making (or reversing) bulk changes, so they can work efficiently. The archivists need to understand the version history of the catalogue so they can be confident about where the information has originated. We now seek a second development specialist to speed up progress on the following work strands: • data extraction and transformation • infrastructure • editorial workflow • API. Who Speclialist Work With The specialist will work with a Technical Architect and two RDF Developers. The core in-house team is a data analyst/Product Manager, a senior archivist and a Service Owner and the Head of Cataloguing, Taxonomy and Data. The specialists will also work with a wider group of users including archivists across the organisation responsible for the management of the catalogue. What Specialists Work On We're developing a pan-archival catalogue, bringing together record descriptions from multiple catalogues into a single new system. A developer is required to join a Technical Architect/another RDF developer to work on the Alpha development. You will join a small team to deliver a new catalogue management system. Involving: developing API functions to search, select, add, export, edit, import, delete catalogue data; developing search for use by expert users (using SPARQL with Elasticsearch); developing an Extract, Transform, Load process to migrate catalogue data from multiple relational database (SQL Server) and RDF databases to a cloud based native RDF database (AWS Neptune). Skills & Experience • Have experience with using standards-based ontologies/vocabularies, such as W3C PROV data model, Dublin Core and W3C ODRL • Have experience of validating RDF data, for example using RDF SHACL • Have experience of creating and working with RDF databases and SPARQL, for example AWS Neptune • Have experience, knowledge and understanding of building Extract, Transform, Load (ETL) processes • Have experience, knowledge of Java/Scala and an understanding of working with mixed content in the context of large, semi-structured datasets • Have experience, knowledge and understanding of implementing resilient and secure systems using IAM in a cloud context Nice to Haves • Have experience developing a user interface/front end to support non-expert, editorial engagement with RDF • Have experience, knowledge and understanding of EAD3 and EAC-CPF Work Location Whilst mainly working remotely, the Catalogue, Taxonomy and Data team is based at The National Archives, Bessant Drive, Richmond, Surrey TW9 4DU Working Arrangments Given the situation with COVID-19, remote working will be the main arrangement for this project. Some work may be conducted at The National Archives, Bessant Drive, Richmond, Surrey TW9 4DU, but only when it is appropriate and safe to do so, eg monthly team work sessions at The National Archives at Kew (a couple of days per month). Security Clearance Baseline security clearance will be required. No. of Specialists to Evaluate 6 Cultural Fit Criteria • Have collaborative and flexible working approach, e.g. working with in-house technical and other digital specialists • Approach to supporting teams to adopt new technologies • Examples of delivering transition, knowledge transfer and handover of code • An appreciation for the importance of technical documentation as a means of ensuring ongoing maintainability of systems • Demonstrable commitment to a diverse working environment, with a team comprised of experts from a wide variety of backgrounds Assessment Method • Reference • Interview Evaluation Weighting Technical competence 60% Cultural fit 20% Price 20% Questions from Suppliers 1.
