Data Discovery Functional Profile
Data discovery enables secondary users to find the types of data available in the ecosystem as well as summary-level information about available data sets.
From inherited abstract Artifact Functional Profile
An artifact is a managed resource within Data Discovery has architectural implications on the Semantic Infrastructure: .
An artifact is associated with Models describe the structural, behavioral, and semantic aspects of data. This requires the following capabilities:
- descriptions to enable the models artifact to be visible, with where the description includes a unique identifier for the model and each of its elements as well as access to a meta-model artifact and a sufficient, and preferably a machine processible, representation of the meaning of terms used to describe the modelartifact, its functions, and its effects;
- one or more discovery mechanisms that enable searching for models and model fragments artifacts that best meet the search criteria specified by the service participant; where the discovery mechanism will have access to the individual model artifact descriptions, possibly through some repository mechanism;
- accessible storage of modelsartifacts and artifact descriptions, so service participants can access, examine, and use the models artifacts as defined.
Descriptions include references to metrics which describe the operational constraints of the data being described. This requires the following capabilities:
- the infrastructure monitoring and reporting information on service data;
- possible interface requirements to make accessible metrics information generated or most easily accessed by the related services;
- mechanisms to catalog and enable discovery of which metrics are available for a modeled data element and information on how these metrics can be accessed;
- mechanisms to catalog and enable discovery of compliance records associated with data elements that are based on these metrics.
From inherited abstract Discovery Functional Profile
Discovery is the set of capabilities which enable searching for artifacts that best meet the search criteria specified by the service participant.
Aspects of discovery include:
- Search for services, policies, and other artifact descriptions accessible via some repository mechanism
- Search for operational characteristics of artifacts, which are metrics defined in artifact descriptions. The information is accessible via infrastructure monitoring capabilties or directly from services.
- Tracking and notification mechanisms related to artifact usage, service availability, operational conformance
Capabilities associated with discovery are delineated in the functional profiles inherited, and specialized, by the discovery profile, namely:
- Artifact
- Metrics
- Interoperability
From inherited abstract Interoperability Functional Profile
Descriptions Models provide up-to-date information on what a data element resource is, the conditions for interacting with the data elementresource, and the results of such interactions. As such, the model description is the source of vital information in establishing willingness to interact with a resource, reachability to make interaction possible, and compliance with relevant conditions of use. This requires the existence of
Architectural implications of interoperability on the Semantic Infrastructure are reflected in the following capabilities:
- one or more discovery mechanisms that enable searching for data elements described resources that best meet the criteria specified by a service participant, where the discovery mechanism will have access to individual modeled descriptions, possibly through some repository mechanism;
- tools to appropriately track users of the modeled descriptions and notify them when a new version of the modeled description is available.
From inherited abstract Metrics Functional Profile
Artifact Descriptions include references to metrics which describe the operational characteristics of the subjects being described
Architectural implications of metrics on the Semantic Infrastructure are reflected in the following capabilities:
- access to platform infrastructure monitoring and reporting capabilities
- access to metrics information generated or accessible by related services
- mechanisms to catalog and enable discovery of which metrics are available for a described artifact and information on how these metrics can be accessed;
- mechanisms to catalog and enable discovery of compliance records associated with policies, contracts, and constraints that are based on these metrics.

Derived From Requirements
- Semantic Infrastructure Requirements::caGRID 2.0 Platform and Terminology Integration::Service Discovery and Utilization This group of requirements focuses on enabling developers of composite services and applications to discover, compose, and invoke services. This includes the discovery of published services based on service metadata and the generation of client APIs in multiple languages to provide cross-platform access to existing services. The platform will use the semantic infrastructure service metadata to address all the service discovery requirements. The semantic infrastructure relies on metadata about services and artifacts. Link to use case satisfied from caGRID 2.0 Roadmap: As institutions share de-identified glioblastoma data sets, they are available to others via data discovery. The treatment recommendation service used by the oncologist is able to discover these new data sets and their corresponding information models, and include that data for subsequent use in recommendation of treatment. Link to use case satisfied from caGRID 2.0 Roadmap: all of the data management and access services in the use case are utilized by application developers to build the user interfaces that the clinicians use during the course of patient care.
