CONTINUOUS CAPTURE OF METADATA

Data Transformation Recorder

Welcome to the Continuous Capture of Metadata tools website, presented by MTNA. If you are familiar with our work and objectives, you can get started right away with our Data Transformation Recorder tool. Read below for information on the platform components, or how to use the underlying web services (API). Visit the C2Metadata project site for more information.

Open-Source Interface

The MTNA Data Transformation Recorder is free to use but leverages proprietary libraries to support its more advanced features. ICPSR has implemented a fully open source version of the Data Transformation Recorder, offering similar capabilities, but without the options to add file level metadata (authors, filenames, and the like).

API Services

The metadata transformation process is broken down into multiple microservices, each accessible by its own API. All of these services are open source, with the source code and a Docker image available for use on GitLab. For your convenience, we are hosing them here under one domain. The URL and available endpoints for each of these services is available in the linked documentation. These projects are still in development, so if you notice a bug, we encourage you to file an issue in the associated GitLab repository.

Structured Data Transformation Language (SDTL)

To facilitate the translation of multiple languages into machine-actionable representations of data transformations, the project team developed an intermediate language called Structured Data Transformation Language (SDTL).
