The U.S. Geological Survey’s (USGS) ownership, responsibility, and accountability for USGS data are evident when USGS scientists use a USGS repository to release their scientific data. In some cases, however, there is value in also serving data through integrated, non-USGS repositories that the USGS deems are trusted or acceptable according to the criteria below.
| Criteria |
How criteria are demonstrated |
| Funding/support for the repository is sustainable. |
Repository documentation lists persistent sources of funding and provides sustainability and succession plans. |
| Data are easily discovered and available free to the public. |
This is stated on repository information page (“About Us”). |
| Commitment to both preserve and serve the data is stated. |
This is stated on repository information page (“About Us”). |
| The USGS is able to retain an official metadata record (in the Science Data Catalog) that can be used to identify the deposited dataset within the larger repository data collection. |
Citation guidance is stated in repository information for data contributors. |
| Data and metadata can be updated, if needed. |
Guidance for updating is stated in repository information for data contributors. |
The following are additional criteria for USGS data managers and data producers to consider in evaluating the suitability of non-USGS repositories.
- Does the repository encourage open or community-based standards and formats that enable automated use of data?
- Does the repository have measures in place to ensure continuous availability?
- Are application program interfaces (APIs) or other web services available for accessing the data? Is there documentation on using APIs and other web services?
- Does the repository use reliable data preservation practices?
- What are the requirements for adding data to the non-USGS repository system? Are they comparable with those for adding data to USGS repositories?
- Does the repository allow attribution to identify data produced by the USGS?
Although no specific certification is required for acceptance as a non-USGS repository, a useful source of standards to follow is available here.
