PROFILE
Marcel Bollmann
Marcel Bollmann developed and maintained core infrastructure for the acl-org/acl-anthology repository, focusing on data modeling, ingestion workflows, and metadata integrity. He implemented robust XML and LaTeX processing pipelines in Python, introducing schema-level validation, enum-based data models, and improved citation export. Marcel enhanced the release process with automated build systems and CI/CD integration, while refining author correction workflows and issue templates to streamline contributor experience. His work included backend development, API design, and extensive test coverage, leveraging technologies such as Pytest and Hugo. These efforts improved data quality, ensured reliable bibliographic exports, and enabled faster, safer release cycles.

Oct 1, 2025October 2025 monthly summary for acl-anthology: Delivered targeted improvements to the author-corrections workflow by refining issue template guidance to emphasize metadata consistency between PDF and web pages and the necessity of using the 'Fix data' action prior to submission. This work enhances data integrity, reduces back-and-forth with authors, and streamlines corrections for the ACL Anthology project.

Dec 1, 2024December 2024 monthly summary for acl-org/acl-anthology. Delivered a breadth of UI, data-model, XML metadata, and tooling improvements that collectively increase data integrity, release reliability, and developer productivity. Key enhancements include UI front-page integration for NoDaLiDa, establishment of the SIGARAB group, and foundational data-model improvements that enable robust comparisons and hashing across core entities. XML serialization and paper metadata were enhanced for better interoperability and future extensibility, including MarkupText.as_xml(), attachments modeled as a list, and explicit journal support at the paper level. Volume metadata was strengthened with include_volumes API exposure, paper issue handling, and DOIs, enabling richer indexing and citation workflows. The team improved loading determinism for XML collections and hardened frontend/escaping behavior, improving data quality and user trust. A build and tooling upgrade (poetry, REPL helpers, explicit type aliases) and a version bump to v0.5.0 with release notes streamlined release processes and improved developer experience. These changes drive business value by improving data accuracy, searchability, and reliability, while enabling faster iteration and safer releases.
