2. Automated private download URLs with any necessary API keys or credentials
3. Hard drives

• For metadata information see 191xx ISO standards and Federal Geographic Data Committee (FGDC)
• To the extent allowed by the underlying format, include available information about how the data was created, collected and any post-processing which has been applied

Project and layer files (.mxd, .qgs, .lry) may be acquired with deposits of content data to assist in reviewing materials during deposit process

Files must contain no measures (such as digital rights management [DRM] or encryption) that control access to or prevent use of the digital work.
