General Questions

How do I change my caDSR password to log into caDSR Tools?

For more information about the caDSR Password Change Station, see Using the caDSR Password Change Station.

Why should I use the Curation Tool versus other tools?

The Curation Tool enables you to search discrete elements of metadata, for example, value domains, data element concepts, and value meanings, independent of their association with other metadata like data elements. The Curation Tool also allows you to update data once you complete a search; if you are looking up a group of data elements, the results display the name of the data element concept and value domain without having to open another screen.

How do I copy a message that appears in the Curation Tool?

To copy a message in a caDSR internet browser, right-click the message.

Why does it appear that when I open and navigate to the Curation Tool that I am still logged in? 

The internet browser retains your login information across sessions.

How do you change a group of common data element's, that is, Block Edit?

From the search results, select the check boxes next to each common data element of interest, then select the Action icon and the graphic in the third column to the right of Edit.

The popup action menu on the Search Results page has three columns.

  1. A column of icons with an empty check box at the top of it. These act on the selected (highlighted) row only allowing single actions without changing or selecting the check boxes.
  2. A column of labels, for example, Edit, View, which do not perform actions. These describe the actions performed by the icons immediately to the left and right of the label.
  3. A column of icons with a selected check box at the top of it. These act on all checked rows and does not include the highlighted row unless it is also checked.

Using the Edit row as an example, the first column icon opens an edit on the highlighted row, the third column icon performs a Block Edit on all checked rows.

Which workflow statuses can be used in designation?

Data elements with any of the following workflow statuses may be designated as Used By a non-owning context:

  • Approved for Trial Use
  • Committee Submitted Used
  • Draft Mod
  • Committee Approved
  • Released-non-compliant
  • Released

Refer also to the caDSR Business Rules.

Data Element Questions

I want to resuse my data elements, but the data element concept of the data element is in the workflow status DRAFT NEW. What should I do?

Check the data element for completeness and ISO compliance and consider changing the workflow status to RELEASED.

Why can't I find the data elements when they should be in the search results?

It is possible that some data elements have not yet been identified for use and so have not been created as metadata in the caDSR. However, here are some example searches that returned results:

In Advanced Search, have All defaulted in the search criteria, and enter the term transcript in the search field.

Enter the term primer in the search field. 

How do I find all data elements that use a specific concept code for either an object class or property?

For example, to find all the data elements that use the EVS concept code of C12727 for an object class or property, search for the Concept Class to return the associated data element concepts.

  • Select Concept Class from the Search For drop down list.
  • Select EVS Identifier from the Search In drop down list.
  • Type in C12727 in the search field.
  • Click Start Search.
  • Select the desired row from the search results.
  • Click Get Associated -> Data Elements.

This search will return the Data Elements that use C12727 as a concept. It could be used as an object class, property, representation term or permissible value for the data elements returned.

What happens if I accidentally create a data element in the wrong context?

You can change the context in the Admin Tool only. If you do not have sufficient user privileges in the Admin Tool, contact Application Support. You will be put in touch with a Preceptor or Metadata Curator with sufficient privileges to change the data element to the correct context.

Data Element Concept Questions

How do I check a data element concept for completeness?

A complete data element concept contains at least one object class and one property, a complete definition, an appropriately descriptive name, a conceptual domain, workflow status, version and begin date. In order for your data element concept to have a workflow status of RELEASED, the object class and property should also have a workflow status of RELEASED.

What do I choose for the conceptual domain for my data element concept or value domain?

A context does not have to create a set of conceptual domains for their own use - all conceptual domains can be reused. Regardless of the owning organization, and as with all metadata, if possible, choose an item with a RELEASED status.

Why am I getting an error today after creating a data element concept yesterday with four concepts, and adding one more concept today?

The database character limit for a Preferred Name is 30, so if you build a long enough object class, property, or Rep Term, the Preferred Name is truncated to 30 characters and may not accommodate the additional Concept.

I versioned a common data element that I own in my context and then created a new version of it. I RETIRED the old version but noticed that other contexts have designated this data element for re-use. What do I do now?

Please contact the Context Administrators for the Using Contexts and let them know about the change.

I created a classification in the Administration Tool and added 10 new data elements. Why can't a colleague review the data elements in the new classification?

You must release your classification scheme to a workflow status of RELEASED. Only RELEASED classification scheme/classification scheme items are displayed in CDE Browser.

Value Domain Questions

Can a non-enumerated value domain have a specific template or format associated with it?

Yes, there are a number of value domain attributes, including Display Format, Minimum and Maximum Value, Minimum and Maximum length that can also be used to refine a non-enumerated value domain.

We do not encourage non-enumerated value domains. We want the value domain to be as specific as possible.

Consider attaching Value Domain Reference Documents where a document can be attached and a specific URL referenced, as well as value domain examples.

Examples provide a way to create a less ambiguous value domain, and in particular, a non-enumerated one. Examples metadata composite an attribute as a caDSR extension of the attributes prescribed for value domains in ISO/IEC 11179-3. Examples can only be attached to value domains using the caDSR Admin Tool.

Do data element concepts, value domains, and their associated common data elements have to have the same name?

No. The value domain and common data element frequently have the same names, but they are not required to be the same or different. Notes: The data element concept does not include a representation, and the common data element does. The common data element and data element concept should NOT have the same preferred and long names.

Can I have more than one value domain per data element?

No, but a single value domain may have one or more permissible values.

A new value domain always has a Modified By and Date Modified, new data elements, et al. have a blank Modified By and Date Modified.

When a value domain is created and the Short Name is marked System Generated, the Curation Tool must update the value domain with the appropriate generated information after it is successfully written to the database and before it is created. This results in the Modified By and Date Modified being updated. Other items do not require this post-process and the Modified By and Date Modified are blank at the end of the create process.

Concept Questions

Why can't I find anything in the caDSR for *exon* and *intron* even though these concepts exist in the NCI Thesaurus and can be used to create metadata.

They should show up as a match if you load a UML model with a class or attribute name containing exon or intron.

How do I reference an EVS concept when I'm curating a classification scheme or conceptual domain?

Use the following conventions.

  • Classification schemes and conceptual domains: Alternate Name. Use the caDSR Admin Tool to add the alternate name. With the Type drop down list and select the appropriate type name depending on the source terminology. If you do not find an appropriate Type code, send an email to NCI CBIIT Application Support asking for the type to be added. The request will be sent to the caDSR development team who can update the Type name list almost immediately during regular business hours.
  • Classification Scheme Items: Comments. Put the concept identifier from the source terminology into the Comments field. Use a semi-colon as a separator, along with the concept's source type name, and any other information that will help us resolve the concept id when the data is converted. The easiest references to resolve will be concept codes from terminologies already served by EVS. For those served by EVS, use the alternate name types already in use in caDSR to minimize research for data conversion. If the source is not an EVS source, include enough information so that NCI CBIIT Application Support can interpret your intent.
