Provide Your Input: Metadata for Legacy Seismic Data Survey
Legacy Seismic Data includes a broad collection of seismic data recorded on paper and magnetic tape some of which also reside on microfiche and microfilm. In this modern digital era of seismology, these data are underutilized. Making these data easily accessible and to meet FAIR (Findable, Accessible, Interoperable, and Resuable) standards requires metadata standards for easily finding and exchanging as well as using this data.
As a first step, participants at a 2019 workshop on seismic legacy data reviewed and added to an initial, proposed set of metadata elements. We are seeking feedback from the broad international seismological community on the revised list. We are asking you to provide your perspective as to which elements should be Required, Recommended, Optional, or Not Included in metadata for legacy seismic data. Our goal is to identify elements that will enable broad reuse of data across a broad federated system of data repositories that wish to make their holdings available to the international seismological community.
It is important to identify enough metadata to make the data FAIR without creating too much work for the curators of the existing legacy data collections. Curators of legacy data collections will be responsible for providing all the Required metadata and the Recommended metadata, if available. The amount of effort will be related to the number of elements so that should be considered as you categorize the various elements.
Please participate in this survey.
