When you search for Common Data Elements (CDEs) in OneData, keep in mind the following points:
- CDEs follow the ISO/IEC 11179 standard, so you can search for data elements using ISO/IEC 11179-based attributes.
- (TBD: Is each field set to "all" by default?)
- Searches are not case sensitive. Searches for
Gene
and gene
return the same results. - In any editable text field, enter a search string, complete or partial. This does not apply to numeric fields such as CDE Public ID.
- In any editable text field, you can use a percent sign (%) as a wildcard. For examples, refer to Using Wildcards - 2021-06-09.
- For some fields, you can adjust the search scope (with options such as IS NULL, IS NOT NULL, NOT LIKE, Exact Phrase Match, All Of The Words, or One Of The Words) by clicking the Advanced Filter icon.
- The system processes search criteria as AND statements, so only CDEs that fulfill all the criteria are returned.
- To reset a list of values, click the Clear Values icon next to that list.
- When you remove or change search criteria, the system does not update search results until you click Apply Filter again.
To perform a data element search:
- Open a supported browser:
Navigate to the following portal:
https://wmonedata.nci.nih.gov/
The home page appears.
From the View menu, select Browse and then select one of the following options:
- Data Elements - View/Browse: Search for data elements used by or owned by any context.
- NCI Standard Data Elements: Search within released data elements that are either owned by or used by the NCI Standards Context. NCI considers these data elements to be standard for the NCI. These elements are a subset of the data elements available in Data Elements- View/Browse.
If necessary, you can clear the saved filter from the upper right corner of the search criteria panel, or select a different one:
- The default saved filter excludes retired (from Workflow Status), excludes test and training (from Owned By), and includes the latest version.
- Another saved filter excludes only test and training (from Owned By).
- Another saved filter includes only test and training (from Owned By).
- To clear the saved filter, set this field to Select a Filter.
