PMHSStyper

PMHSStyper is a fictional open-source software framework designed to provide a typed data processing pipeline for PMHS datasets. It aims to support type safety, schema-driven validation, and repeatable data transformations within computational humanities research.

The core goal of PMHSStyper is to enable researchers to declare PMHS data schemas, enforce constraints, and automatically transform raw input into a typed representation. It emphasizes reproducibility, interoperability, and ease of integration with common data formats used in the PMHS domain, such as JSON, CSV, and RDF.

Key components include a schema language for PMHS data, a runtime validator, and a transformation engine. The schema language, termed PMHS-TL, allows users to define data kinds, fields, relationships, and validation rules, including inheritance and optional fields. The runtime validates incoming data against the PMHS-TL definitions and can generate typed records or export results to chosen formats. The transformation engine supports mapping from heterogeneous sources into standardized PMHS records and can chain pipelines for cleaning, enrichment, and export.

Architecture is modular, featuring a validator, a transformer, an adapter layer, and a plugin system for extending PMHS data kinds. It provides bindings for common programming environments and a command-line interface for scripting data workflows.

History and usage notes indicate PMHSStyper was conceived in the PMHS community to illustrate schema-driven data handling. It has seen several largely community-driven releases and is discussed in literature on data standards and reproducible workflows in the computational humanities.
