When a user creates a collection (at the asset level or higher), that user can specify which groups can modify the metadata for that collection. If you belong to one of those groups, you can modify the metadata for that collection. Keyword searches find assets based on metadata at the asset level or higher.

To edit metadata of a program, study, or asset collection:

  1. Log in, as described in Logging In. 
  2. You have the following choices:
    • To edit the metadata of any collection:
      1. Click Upload in the header. The upload page appears.
      2. Navigate to and select the collection that you want to edit. Click the edit option. (For example, to edit an asset, select a program from the program list, select a study from the study list, select the asset from the asset list, and then select Edit Asset.) The User Metadata page appears with the collection name.
    • To edit the metadata of a collection that contains files:
      1. Perform a search, as described in Finding Data. In the search results, each entry lists the relevant collections (program, study, and asset). An edit icon appears next to each of your collections.
      2. Click the edit icon next to the collection of interest. The User Metadata page appears with the collection name.
  3. Specify the information for the collection:
    • To add a metadata attribute, click Add Metadata. A blank attribute row appears. Specify a unique attribute name. (Repeat for additional attributes.)
    • To delete a new attribute, or to clear the value field for an existing optional attribute, click the X. 
    • For a dataset: Specify whether you want it to be a reference dataset for model analysis. For details, refer to Adding a Reference Dataset.
    • For a model: Specify whether it is deployed in the MoDaC environment for model analysis. (In the Is Model Deployed field, select Yes or No.)
    • Specify a value for each required metadata attribute. Keep in mind the following points: 
      • The character limit for each metadata value is 2700. 
      • The identifier attribute is read-only.
      • If an attribute value begins with http or https, MoDaC displays it as a hyperlink in read-only fields.
      • Specify one of the following curation statuses:
        • Unverified: The curation is current but not reviewed.
        • Pending: Curation is pending on the recommended changes.
  4. Click Update.

To edit metadata of a collection within an asset:

  1. Log in, as described in Logging In. 
  2. Perform a search, as described in Finding Data.
  3. In the search results, click the link for the asset of interest. The Asset Details page appears. 
  4. If the asset has subfolders, navigate to the folder of interest. (Click each folder to open it.)
  5. In the row of the folder for which you want to edit metadata, click the edit icon. The User Metadata page appears with the folder name.
  6. Specify the information for the folder:
    • To add a metadata attribute, click Add Metadata. A blank attribute row appears. Specify a unique attribute name. (Repeat for additional attributes.)
    • To delete a new attribute, or to clear the value field for an existing optional attribute, click the X.
    • Specify a value for each required metadata attribute. Keep in mind the following points: 
      • The character limit for each metadata value is 2700. 
      • If an attribute value begins with http or https, MoDaC displays it as a hyperlink in read-only fields.
      • Specify one of the following curation statuses:
        • Unverified: The curation is current but not reviewed.
        • Pending: Curation is pending on the recommended changes.
  7. Click Update. A message appears, confirming the update. 

To return to the Asset Details page, click Back to Asset Details. To view the metadata (one hour after the update), on the Asset Details page, click the metadata icon next to the folder name.
