h4. Summary

h5. Description of the profile

There were more requests for various types of extensibility than any other category of request other than improvements to tool interfaces. caBIG users and other stakeholders articulated a compelling business need to readily extend models, terminologies, and data elements in a variety of ways.

|Artifact lifecycle management and metadata requirements include the ability to:       * Manage lifecycle, governance and versioning of the models, content and forms      * Establish relationships and dependencies between models, content and forms          * Determine provenance, jurisdiction, authority and intellectual property          * Create represention and views of the information, realized through the appropriate transforms          * Provide access control and other security constraints          * Create annotations for better discovery and searching of artifacts          * Develop usage scenarios and context for the information          * Provide terminology and value set binding  The artifacts are bound to the services via the service metadata. The service metadata combined with the artifacts and supporting metadata provide a comprehensive service specification.    The artifact management requirements listed above are derived from the following use cases:   * _caEHR_: The caEHR project has adopted ECCF for specifications and CDA documents for interoperability. The caEHR project requirements include the need for an infrastructure for managing all the artifacts generated during specification process, including HL7 models and documents. The caEHR project also intends to publish these artifacts for the community and vendors. The infrastructure needs to support better discovery, making all the relevant information available in the right context.   * _ONC and other external EHR adopters_: ONC has adopted CCD and CCR for meaningful use. All national EHR implementations are expected to support forms and the semantics of these forms play a critical role in interoperability. The semantic infrastructure must provide a mechanism to create, store and manage these forms.   * _Clinical Trials_: Clinical trials use forms to capture clinical information, and the semantics captured by these forms are critical for interoperability and reporting. The semantic infrastructure must provide a mechanism to manage the lifecycle of these forms. |Semantic Infrastructure Requirements::Artifact Management::{anchor:_16_5_1_24a0131_1283090023842_213150_4485}Artifact Lifecycle Management|{li}[dynamicDataSetDefinition|#EAID_2D00C6FB_7424_4f0c_8495_BF133FECEC38]{li}{li}[localizeTerminologies|#EAID_8AC09A63_C352_492d_B61D_57F0F3FF1611]{li}{li}[runtimeDataElementAddition|#EAID_BBCDB8E0_BE0E_4b48_B996_DE65026D033D]{li}{li}[localizeElements|#EAID_016B8D23_8DF5_4b4e_9185_7B16D1730BFF]{li}{li}[ushikMetadataRegistryAPI|#EAID_98F28F8F_FB0D_4f83_926B_CA9AB85B556E]{li}{li}[externalResearchCommunityInteroperation|#EAID_5956E11D_A7F8_4f9f_8B8D_406A5FE77356]{li}{li}[ucumUnitsOfMeasureAPI|#EAID_B5CC5FC8_E1BF_40a2_8E74_D13574DFC0D3]{li}{li}[binaryData|#EAID_B516CD5C_5178_460d_A595_BC1ACDECE59D]{li}{li}[dataModelExtensibility|#EAID_15755B4A_BAA7_438d_A9E6_6FC3AB23C894]{li}{li}[internationalization|#EAID_287D754C_827E_44e7_828F_612996254969]{li}|	
|There is a need to support extensions to the existing caDSR UML model and its exposure of these extensions as an API without the need for writing new caDSR code in the original application.  Local data models are dynamic; a change in previously curated data model (e.g., clinical trial schema) can take months and involve lots of people.  A faster way to update the caDSR CDEs and their value domains to better reflect the semantics of local information models is desired.  A good place to start supporting extensions is in the ability to change permissible value sets in the clinical domain.  The underlying motivations for these capabilities include:    * Pathology, imaging, and clinical data elements are required to annotate biospecimens, patient/participant encounters, and patients/participants are unique to the complex disease being studied.   * Even if the existing model is comprehensive enough, cutting edge research will continue to demand the comprehensive capture of new kinds of data (e.g. a novel, predicted biomarker for prostate cancer).   * Users may also want to capture associated information that may be institution-specific and will not be shared (e.g. a freezer’s maintenance contract # and support end date).   *Source:  *   * caDSR documentation   * Interview 5/24/2010,  Dianne Reeves |Gap Analysis::caDSR::{anchor:_16_5_1_24a0131_1283073544119_777120_4016}caDSR-7 - Support data model extensibility|{li}[dataModelExtensibility|#EAID_15755B4A_BAA7_438d_A9E6_6FC3AB23C894]{li}|
