Meeting objectives: 

Increasingly, research and hence socio-economic and technical challenges require integration/interoperation of data. This requires processes to align the data in terms of appropriate values, accuracy, precision across datasets, which in turn requires mapping of metadata schemas describing the datasets to a common canonical form.  This is generally known as cross-walking.  The meeting will discuss existing cross-walking resources including documented mappings and tools, some of which are in the Metadata Standards Catalog (MSC) of the RDA, how they can be supplemented by new schemas and crosswalks, and how the crosswalk specifications and tools can be used to (semi-)automate actual data conversion to achieve integrated, interoperable, cross-domain data assets.

Brief introduction describing the activities and scope of the group: 

The Metadata Interest Group (MIG) is supported by individuals and organizations involved in the development, implementation, and use of metadata for scientific data.  MIG’s chief objective is to identify and endorse metadata solutions for addressing data management challenges. Metadata is crucial for the discovery, access, preservation, exchange, manipulation, and use/re-use of research data.  Metadata discussions frequently focus on community-specific issues such as discipline-specific standards; however, there are dimensions of metadata that are of general interest, cross disciplines, and are amenable to broad community input.  MIG endorses metadata solutions that balance domain-specific and interdisciplinary needs.

MIG has proposed metadata ‘packages’ for the commonly required purposes; a ‘package’ consists of elements (attributes or data structures) the values of which relate to the unique identity of the dataset or record (instance).  To assure machine processing a formal syntax and declared semantics are required, and the packages must exhibit referential and functional integrity as well as human readability. This Metadata Element Set is intended to become an RDA recommendation. The element set has been shared with and reviewed by many of the RDA domain groups.

Short Group Status: 

The Metadata Interest Group (MIG) is a recognized and endorsed RDA group. The group was approved in 2013 and has initiated 2 successful Working Groups, the Metadata Standards Directory Working and the Metadata Standards Catalog Working Group. MIG serves as an umbrella group for various metadata projects.
