SOA Repository Artifact Model and Protocol

OASIS specification known as S-RAMP defines ● a common data model for Artifact

Repositories (SOA focus) (type & model)● an interaction ATOM protocol to facilitate

the use of common tooling and sharing data

S-RAMP Components

● Core Models storing standard metadata and the file content itself

● Derived Models are read only and data is derived from the content

● Extensible● XPath2 based QL

S-RAMP ATOM BIND API

Derived Models(Read Only)

Core Model Documents

XML, XSD, WSDL, SOAP,Policy, ..., Extended Doc

XSD, WSDL, SOAP, Policy, ..., Extended Model

S-RAMP Implementation

● RESTEasy for the ATOM BIND API

● Content Extractors (jar)● Artifact Relationships● Content Derivers● Modeshape and Infinispan

as JCR impl for perform- ance and scalability

● JAAS, SAML for SSO

ATOM BINDING (RESTEasy)

Derived Models(Read Only)

Core Model Documents

JCR Storage (Modeshape on top of Infinispan)

S-RAMP Capabilities?● Store Content and MetaData

○ Core & Custom Properties○ Classification (OWL Ontology)○ Relationships between artifacts

● Rich Query Support XPath2 Style● ATOM API for easy communication

What S-RAMP is not

● SCM - use GIT instead (S-RAMP tracks 'deployable' and 'interface' type artifacts)

● Not meant for intermediate artifacts, but rather 'released' and 'versioned'.

How to interact with S-RAMP?Through the ATOM BIND REST API using ● An ATOM client● Java, using the S-RAMP client library● Command Line Interface● S-RAMP-UI Browser (Web Based)● Maven (S-RAMP Wagon up/down)

S-RAMP ClientSrampAtomApiClient client =

new SrampAtomApiClient(endpoint, username, password, true);

//Upload an artifactBaseArtifactType artifact = client.uploadArtifact(type, is, file);

//Query S-RAMPQueryResultSet rs = client.buildQuery("/s-ramp[@from-demo = ?]")

S-RAMP Demos

DTGov

jboss.org/overlord

Design Time Governance● SOA Architecture Design (Workflow)● Search for Services (re-use)● Artifact Relationship Visualization● Notifications on Service Change● Impact Discovery● Store and Manage Policies

DTGov, some key priorities to start

● Best practice BPMN2 based governance workflows○ Repository events kick off governance workflows

○ Out-of-the-box integration with jBPM-6

○ Workflows can be customized or new ones can be created

● Governance Workflows can push artifacts to a service execution environment using either JON/RHQ, or direct deployment

● DTGov console

Deployment workflow● S-RAMP triggers deploy to runtime● Logs deployment status in S-RAMP● Sends out notifications● Human task to approve or fail● target: dev, qa, stage, prod

DTGov Demo

● Upload ontologies & workflows● 2. Upload Switchyard app using maven

○ s-ramp:query "/s-ramp/ext/SwitchyardApplication"

● 3. Approve SY Artifact(s)

RTGov

jboss.org/overlord

Runtime GovernanceThe RTGov architecture has following goals:● Real-time analysis of individual business transactions

○ correlating activities across services to understand the overall transaction

● Evaluating activity against Service Level Agreements● Real-time policy enforcement

What's Coming (Soon)?Repository:

Complete implementation of S-RAMP-1.0 specIntegration into other JBoss products (TEIID, JON/RHQ) (Done)

Governance:Console (Started)
