Brianna,

Thank you for reaching out with your inquiry regarding common metadata fields in the context of the DCAT-US specification. Below, I have outlined the relevant sections from the DCAT-US documentation that correspond to your requirements:

  1. Source of the Metadata / Provider: For identifying the source or provider of the metadata, the dct:creator property is used in the DCAT-US specification. This property specifies an entity primarily responsible for making the resource. You can find more details in the section on Stakeholders and Resource Attributions.

  2. Dataset Title: The dataset title can be specified using the dct:title property, which provides a descriptive name to the dataset. Further information is available under Dataset Title.

  3. Date/Time Information: To represent date/time information, the properties dct:temporal, dct:issued, and dct:modified are used. These fields capture relevant temporal data about the dataset. Please see Dataset Temporal Coverage for more specifics.

  4. Storage Volume: The dcat:byteSize property indicates the size of the dataset's distribution in bytes, providing an estimate of the required storage volume. Details on this can be found in Distribution Byte Size.

  5. Useful Hyperlinks: For hyperlinks to access or download the dataset, dcat:accessURL and dcat:downloadURL are the relevant properties. These are detailed in the section on Distribution Metadata.

Given your role at NOAA/NOS and the mention of ISO 19115-2 and CSDGM, it’s crucial to consider specific adaptations or mappings to align DCAT-US with these geospatial metadata standards. For a comprehensive understanding of how DCAT-US can be applied within NOAA's context, I recommend reviewing the entire DCAT-US specification, alongside any NOAA-specific metadata management guidelines.
