Create new data elements at runtime
Use Case Number |
Init1hm2.pm6.1 |
Brief Description |
Users of systems that are designed to collect data items may need to collect data elements that were not previously described by metadata. In this case, it is necessary that the user is able to create the metadata necessary to begin data capture. |
Actor(s) for this particular use case |
Metadata Specialist |
Pre-condition |
Metadata for a data element does not exist |
Post condition |
Metadata for the data element exists and data can be captured |

Fit criterion/Acceptance Criterion |
The data element is stored locally for reuse in local cancer center systems. It contains all the necessary metadata for sharing data (next use case). |
Share data elements at runtime
Use Case Number |
Init1hm2.pm6.2 |
Brief Description |
Once data elements are dynamically created for local use in data capture, it is necessary to publish the metadata for data sharing. It may be necessary to harmonize the metadata with other systems, but it is desirable that the metadata be managed at least locally. |
Actor(s) for this particular use case |
Metadata Specialist |
Pre-condition |
The data element is locally available. |
Post condition |
The data element is shared with other organizations in a distributed fashion and contains all metadata necessary for data sharing. |
Steps to take |
|
Alternate Flow |
None. |

Fit criterion/Acceptance Criterion |
The data elements are available to other researchers for reuse, and all metadata necessary for data sharing is available. |
Reuse data elements at runtime
Use Case Number |
Init1hm2.pm6.3 |
Brief Description |
Data elements that have been created dynamically locally and shared should be reusable by other researchers and organizations. Users should be able to browse for, select, and reuse them in their data collection forms. |
Actor(s) for this particular use case |
Metadata Specialist |
Pre-condition |
Data elements are shared by other users in other organizations. |
Post condition |
Shared data elements are reused for data collection. |
Steps to take |
