Making MagIC More FAIR with Structured Metadata
Abstract
The Magnetics Information Consortium (MagIC) developed and maintains a database and web application for supporting the paleo-, geo-, and rock magnetic scientific communities (https://earthref.org/MagIC). Grants from the National Science Foundation have generously and continuously supported MagIC since 2003 including a recent award to support further development. One of the primary objectives of this award is to make MagIC more Findable, Accessible, Interoperable, and Reusable (FAIR). Part of this effort is addressed with the introduction of structured metadata objects for the MagIC contribution landing pages to expose standardized machine-readable descriptions of the database content.
MagIC consists of over 4,000 versioned datasets, each with a unique publication describing the sampling and analysis methods. These datasets adhere to the MagIC Data Model (https://earthref.org/MagIC/data-models/3.0) hierarchy from millions of raw instrument measurements to thousands of sample results to location averages and contribution metadata. Curating a collection of published scientific results in a consistent format allows MagIC to support new transformative science. The MagIC search interface can interrogate a significant portion of this community's results over the last century and combine these data to address grand challenges in paleo-, geo-, and rock magnetics. In the last few months, MagIC began annotating these valuable datasets with structured JSON-LD metadata using Schema.org vocabularies to make them more findable and accessible. EarthCube's Project 418 (https://geodex.org) and Google Search are indexing these annotations and MagIC continues to add metadata to the JSON-LD objects. The MagIC web application (https://github.com/earthref/MagIC) is developed with a permissive license and the datasets downloaded from MagIC are compatible with the open-source PmagPy (https://github.com/PmagPy/PmagPy) paleomagnetic analysis software.- Publication:
