{scrollbar} {children} h3. {page-info:title} h4. Summary h5. Description of the profile A policy represents some constraint or condition on the use, deployment or description of a resource as defined by a participant or, more generally, a stakeholder. A permission constraint governs the ability of a participant or other actor to perform an action or enter some specified state. The ability to *extend* a service specification, including any associated model artifact, is subject to the permission policies embodied in the contract between the participants. Permissions may apply to any action that any actor may be able to perform. A contract is a constraint that has the agreement of the constrained participants. A policy constraint is a measurable proposition that characterizes the constraint that the policy is about. Multiple policies may be defined for one or more services in one or more ownership domains. The application of policies and contracts over distributed services requires the ability to compose one or more policies into an overarching policy. The composition of policies may be implemented as a hierarchy and/or it can be implemented as intersections and unions of sets. The analysis of policy rules may result in conflicts between the policy rules. There can be many causes for policy conflicts such as conflicting policy rules between ownership domains and policy language specifications that do not convert to first order predicate logic for IT policy mechanisms. This can cause policy decision results to be indeterminate. Policy administration mechanisms may provide conflict resolution capabilities prior to the storage/distribution of policies. At run time, conflicts may propagate to higher authorities inside or outside the SOA-based IT mechanisms. The architectural implications of Policy and Contract may be summarized as: constraints must be measurable, enforceable, auditable, administered, expressed in a formal constraint language, distributed, stored, accessible and conflicts must be detectable. 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. *Extend* specializes capabilities architecturally implied by its associated concepts of Artifact , Change , Composition , Interaction , Interoperability , Metrics , Policy , PolicyAndContract , PolicyAndContractLanguage . The implied architectural capabilities are described in the following paragraphs. *Artifact* An artifact is a managed resource within the Semantic Infrastructure. An artifact is associated with the following capabilities: * descriptions to enable the artifact to be visible, where the description includes a unique identifier for the artifact and a sufficient, and preferably a machine processible, representation of the meaning of terms used to describe the artifact, its functions, and its effects; * one or more discovery mechanisms that enable searching for artifacts that best meet the search criteria specified by the service participant; where the discovery mechanism will have access to the individual artifact descriptions, possibly through some repository mechanism; * accessible storage of artifacts and artifact descriptions, so service participants can access, examine, and use the artifacts as defined. *Change* Artifact descriptions change over time and their contents will reflect changing needs and context. Architectural implications of change on the Semantic Infrastructure are reflected in the following capabilities: * mechanisms to support the storage, referencing, and access to normative definitions of one or more versioning schemes that may be applied to identify different aggregations of descriptive information, where the different schemes may be versions of a versioning scheme itself; * configuration management mechanisms to capture the contents of the each aggregation and apply a unique identifier in a manner consistent with an identified versioning scheme; * one or more mechanisms to support the storage, referencing, and access to conversion relationships between versioning schemes, and the mechanisms to carry out such conversions. *Composition* Artifact Descriptions may capture very focused information subsets or can be an aggregate of numerous component descriptions. Service description is an example of a likely aggregate for which manual maintenance of all aspects would not be feasible. Architectural implications of composition on the Semantic Infrastructure are reflected in the following capabilities: * tools to facilitate identifying description elements that are to be aggregated to assemble the composite description; * tools to facilitate identifying the sources of information to associate with the description elements; * tools to collect the identified description elements and their associated sources into a standard, referenceable format that can support general access and understanding; * tools to automatically update the composite description as the component sources change, and to consistently apply versioning schemes to identify the new description contents and the type and significance of change that occurred. *Interaction* Descriptions of interactions are important for enabling auditability and repeatability, thereby establishing a context for results and support for understanding observed change in performance or results. Infrastructure services provide mechanisms to support service interaction. Architectural implications of interactions on the Semantic Infrastructure are reflected in the following capabilities: * one or more mechanisms to capture, describe, store, discover, and retrieve interaction logs, execution contexts, and the combined interaction descriptions; * one or more mechanisms for attaching to any results the means to identify and retrieve the interaction description under which the results were generated. * mediation services such as message and event brokers, providers, and/or buses that provide message translation/transformation, gateway capability, message persistence, reliable message delivery, and/or intelligent routing semantics; * binding services that support translation and transformation of multiple application-level protocols to standard network transport protocols; * auditing and logging services that provide a data store and mechanism to record information related to service interaction activity such as message traffic patterns, security violations, and service contract and policy violations * security services that abstract techniques such as public key cryptography, secure networks, virus protection, etc., which provide protection against common security threats in a SOA ecosystem; * monitoring services such as hardware and software mechanisms that both monitor the performance of systems that host services and network traffic during service interaction, and are capable of generating regular monitoring reports. *Interoperability* Descriptions provide up-to-date information on what a resource is, the conditions for interacting with the resource, and the results of such interactions. As such, the 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. Architectural implications of interoperability on the Semantic Infrastructure are reflected in the following capabilities: * one or more discovery mechanisms that enable searching for described resources that best meet the criteria specified by a service participant, where the discovery mechanism will have access to individual descriptions, possibly through some repository mechanism; * tools to appropriately track users of the descriptions and notify them when a new version of the description is available. *Metrics* 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. *Policy* Artifact Descriptions include references to policies defining conditions of use and optionally contracts representing agreement on policies and other conditions. Architectural implications of policy on the Semantic Infrastructure are reflected in the following capabilities: * descriptions to enable the policy modules to be visible, where the description includes a unique identifier for the policy and a sufficient, and preferably a machine processible, representation of the meaning of terms used to describe the policy, its functions, and its effects; * one or more discovery mechanisms that enable searching for policies that best meet the search criteria specified by the service participant; where the discovery mechanism will have access to the individual policy descriptions, possibly through some repository mechanism; * accessible storage of policies and policy descriptions, so service participants can access, examine, and use the policies as defined. Policy capabilities are specialization of Artifact capabilities. *PolicyAndContract* While policy and contract descriptions have much of the same architectural implications as Service Descriptions, mechanisms supporting policies and contracts also have the following architectural implications: * decision procedures which must be able to measure and render decisions on constraints; * enforcement of decisions; * measurement and notification of obligation constraints; * auditability of decisions, enforcement, and obligation measurements; * administration of policy and contract language artifacts; * storage of policies and contracts; * distribution of policies/contracts; * conflict resolution or elevation of conflicts in policy rules; * delegation of policy authority to agents acting on behalf of a client; * decision procedures capable of incorporating roles and/or attributes for rendered decisions. *PolicyAndContractLanguage* While policy and contract descriptions have much of the same architectural implications as Service Descriptions, languages supporting policies and contracts also have the following architectural implications: * expression of assertion and commitment policy constraints; * expression of positive and negative policy constraints; * expression of permission and obligation policy constraints; * nesting of policy constraints allowing for abstractions and refinements of a policy constraint; * definition of alternative policy constraints to allow for the selection of compatible policy constraints for a consumer and provider; * composition of policies to combine one or more policies. h5.

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}| |The Knowledge Repository should provide appropriate references and/or attributes to enable the use of all objects internationally.

An interaction can be characterized by a sequence of actions. Consequently, interacting with a service, i.e. performing actions against the service—usually mediated by a series of message exchanges—involves actions performed by the service. Different modes of interaction are possible such as modifying the shared state of a resource. Note that a participant (or agent acting on behalf of the participant) can be the sender of a message, the receiver of a message, or both. Interacting with Services has the following architectural implications on mechanisms that facilitate service interaction: _A well-defined service Information Model, as elaborated in the inherited Information Model profile._ _A well-defined service Behavior Model, as elaborated in the inherited Behavior Model profile._ _Service composition mechanisms to support orchestration of service-oriented business processes and choreography of service-oriented business collaborations, as elaborated in the inherited Service Composition profile._ _Infrastructure services that provides mechanisms to support service interaction, as elaborated in the inherited Interaction profile._ _A layered and tiered service component architecture that supports multiple message exchange patterns (MEPs)l, as elaborated in the inherited Message Exchange profile._ |Semantic Profile::OASIS SOA::{anchor:_16_5_1_24a0131_1283763631267_880282_4612}Interacting with Services Model|{li}[interactionLog|#_16_5_1_24a0131_1283703044067_803205_3257] *from inherited abstract profile* Interaction{li}{li}[interactionResults|#_16_5_1_24a0131_1283703044069_331285_3258] *from inherited abstract profile* Interaction{li}{li}[mediation|#_16_5_1_24a0131_1283774410554_993474_5418] *from inherited abstract profile* Interaction{li}{li}[binding|#_16_5_1_24a0131_1283774411368_995660_5431] *from inherited abstract profile* Interaction{li}{li}[logging|#_16_5_1_24a0131_1283774412029_665259_5444] *from inherited abstract profile* Interaction{li}{li}[security|#_16_5_1_24a0131_1283774412802_440973_5457] *from inherited abstract profile* Interaction{li}{li}[monitoring|#_16_5_1_24a0131_1283774413444_304515_5470] *from inherited abstract profile* Interaction{li}| |Artifact Descriptions include references to policies defining conditions of use and optionally contracts representing agreement on policies and other conditions.

This includes not only the information and behavior models associated with a service to define the service interface but also includes information needed to decide whether the service is appropriate for the current needs of the service consumer. Thus, the service description will also include information such as service reachability, service functionality, and the policies and contracts associated with a service. A service description artifact may be a single document or it may be an interlinked set of documents. Architectural implications of service description on the Semantic Infrastructure are reflected in the following functional decomposition: * Description will change over time and its contents will reflect changing needs and context. This is elaborated in the inherited Change profile. * Description makes use of defined semantics, where the semantics may be used for categorization or providing other property and value information for description classes. This is elaborated in the inherited Semantic Model profile. * Descriptions include reference to policies defining conditions of use and optionally contracts representing agreement on policies and other conditions. This is elaborated in the inherited Policy profile. * Descriptions include references to metrics which describe the operational characteristics of the subjects being described. This is elaborated in the inherited Metrics profile. * Descriptions of the interactions are important for enabling auditability and repeatability, thereby establishing a context for results and support for understanding observed change in performance or results. This is elaborated in the inherited Interaction profile. * Descriptions may capture very focused information subsets or can be an aggregate of numerous component descriptions. Service description is an example of a likely aggregate for which manual maintenance of all aspects would not be feasible. This is elaborated in the inherited Composition profile. * Descriptions provide up-to-date information on what a resource is, the conditions for interacting with the resource, and the results of such interactions. As such, the 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 is elaborated in the inherited Interoperability profile. Policy capabilities are specialization of Artifact capabilities. |Semantic Profile::OASIS SOA::{anchor:_16_5_1_24a0131_1283763560612_868976_4608}Service Description Model|{li}[versioning|#_16_5_1_24a0131_1283699095521_961509_3106] *from inherited abstract profile* Change{li}{li}[configurationManagement|#_16_5_1_24a0131_1283700133655_905377_3117] *from inherited abstract profile* Change{li}{li}[transition|#_16_5_1_24a0131_1283700246486_44421_3128] *from inherited abstract profile* Change{li}{li}[discovery|#_16_5_1_24a0131_1283714222600_103266_4106] *from inherited abstract profile* Artifact{li}{li}[identity|#_16_5_1_24a0131_1283714222601_506267_4107] *from inherited abstract profile* Artifact{li}{li}[metadata|#_16_5_1_24a0131_1283714222603_853936_4108] *from inherited abstract profile* Artifact{li}{li}[store|#_16_5_1_24a0131_1283714222609_981432_4109] *from inherited abstract profile* Artifact{li}{li}[monitor|#_16_5_1_24a0131_1283702219067_789210_3209] *from inherited abstract profile* Metrics{li}{li}[metrics|#_16_5_1_24a0131_1283702219069_775824_3210] *from inherited abstract profile* Metrics{li}{li}[metricsDiscovery|#_16_5_1_24a0131_1283702219071_411273_3211] *from inherited abstract profile* Metrics{li}{li}[complianceDiscovery|#_16_5_1_24a0131_1283702219073_894098_3212] *from inherited abstract profile* Metrics{li}{li}[interactionLog|#_16_5_1_24a0131_1283703044067_803205_3257] *from inherited abstract profile* Interaction{li}{li}[interactionResults|#_16_5_1_24a0131_1283703044069_331285_3258] *from inherited abstract profile* Interaction{li}{li}[compositionArchive|#_16_5_1_24a0131_1283703443770_810122_3292] *from inherited abstract profile* Composition{li}{li}[assembly|#_16_5_1_24a0131_1283703443772_860088_3293] *from inherited abstract profile* Composition{li}{li}[compositionChange|#_16_5_1_24a0131_1283703443775_178969_3294] *from inherited abstract profile* Composition{li}{li}[componentAcquisition|#_16_5_1_24a0131_1283704509983_673729_3325] *from inherited abstract profile* Composition{li}{li}[interoperabilityDiscovery|#_16_5_1_24a0131_1283704952692_78857_3340] *from inherited abstract profile* Interoperability{li}{li}[serviceChangeNotification|#_16_5_1_24a0131_1283704952697_176583_3341] *from inherited abstract profile* Interoperability{li}| |One of the key requirements for participants interacting with each other in the context of a SOA is achieving visibility: before services can interoperate, the participants have to be visible to each other using whatever means are appropriate. The Reference Model analyzes visibility in terms of awareness, willingness, and reachability. Visibility in a SOA ecosystem has the following architectural implications on mechanisms providing support for awareness, willingness, and reachability: _Mechanisms providing support for awareness will likely have the following minimum capabilities:_ * creation of Description, preferably conforming to a standard Description format and structure; * publishing of Description directly to a consumer or through a third party mediator; * discovery of Description, preferably conforming to a standard for Description discovery; * notification of Description updates or notification of the addition of new and relevant Descriptions; * classification of Description elements according to standardized classification schemes. _In a SOA ecosystem with complex social structures, awareness may be provided for specific communities of interest. The architectural mechanisms for providing awareness to communities of interest will require support for:_ * policies that allow dynamic formation of communities of interest; * trust that awareness can be provided for and only for specific communities of interest, the bases of which is typically built on keying and encryption technology. _The architectural mechanisms for determining willingness to interact will require support for:_ * verification of identity and credentials of the provider and/or consumer; * access to and understanding of description; * inspection of functionality and capabilities; * inspection of policies and/or contracts. _The architectural mechanisms for establishing reachability will require support for:_ * the location or address of an endpoint; * verification and use of a service interface by means of a communication protocol; * determination of presence with an endpoint which may only be determined at the point interaction but may be further aided by the use of a presence protocol for which the endpoints actively participate. |Semantic Profile::OASIS SOA::{anchor:_16_5_1_24a0131_1283763628053_328597_4610}Service Visibility Model|{li}[discovery|#_16_5_1_24a0131_1283714222600_103266_4106] *from inherited abstract profile* Artifact{li}| h4. {anchor:_16_5_1_24a0131_1283703443772_860088_3293}assembly h5.

Description While the Resource identity provides the means to know which subject and subject description are being considered, Provenance as related to the Description class provides information that reflects on the quality or usability of the subject. Provenance specifically identifies the entity (human, defined role, organization, ...) that assumes responsibility for the resource being described and tracks historic information that establishes a context for understanding what the resource provides and how it has changed over time. Responsibilities may be directly assumed by the Stakeholder who owns a Resource or the Owner may designate Responsible Parties for the various aspects of maintaining the resource and provisioning it for use by others. There may be more than one entity identified under Responsible Parties; for example, one entity may be responsible for code maintenance while another is responsible for provisioning of the executable code. The historical aspects may also have multiple entries, such as when and how data was collected and when and how it was subsequently processed, and as with other elements of description, may provide links to other assets maintained by the Resource owner. h5.
