Engineering Use Cases

GEOSS Architecture Implementation Pilot Phase 3‎ > ‎

Engineering Use Cases

This page lists engineering use cases or functional activities intended to be (re)used and specialized as steps in AIP-3 community scenarios. Each use case is linked to a description page and is also cross-referenced on the main AIP-3 page to the scenario steps in which it is included. The present list has been updated and extended from the initial work in AIP-2. A summary table in docx format is here. The AIP-3 engineering use cases engineering report is here.

The use cases are sorted according to "number". The base use cases are identified by letter and reusable child use cases by adding a decimal number (e.g. C.2). A diagram of the 15 base use cases as refined in AIP-3 is shown below:

Enterprise Actors

GEOSS User	Discovers, consumes, and exploits GEOSS resources	Base Actor
GEOSS Provider	Deploys, Describes, Registers GEOSS Resources	Base Actor
GEOSS Integrator	Builds, configures, registers applications to work with GEOSS services	Base Actor
GCI Operator	Operators GCI components, reviews and approves registrations	Base Actor

Order	Use Case Name	Description	GCI Components	Actors
Sort	Sort	Sort	Sort	Sort


A	Register Resources	Register components and services in the CSR or community catalog	Component & Services Registry, Community Catalog	GEOSS Provider
B	Deploy Resources	Configure and deploy a component with associated services	BPW	GEOSS Provider
C	Harvest & Query Metadata Via Clearinghouse	Harvest and/or query metadata from community catalogues	CSR, Clearinghouse	GCI Operator
D	Client Search of Metadata	Search for resources in Registry, Clearinghouse and Community Catalogs	CSR, Clearinghouse, +/- GEO Portal	GEOSS User
E	Presentation of Reachable Services & Alerts	User presentation of information about available services, workflows, and alerts	GEO Portal	GEOSS User
F	Interact With Services	Activity of client to consume services for datasets, sensors, models, workflows, etc.	GEO Portal	GEOSS User, Application client
G	Exploit Data Visually & Analytically	Use portals and clients to present data in useful ways for interpretation and decision support	BPW	GEOSS User
H	Construct Processing Service	Design, implement, compose (if composite), deploy, and publish a processing service	CSR	GEOSS Integrator
I	Test Services	Test services for conformance and QoS. Testing may be occur before or after services are registered	CSR, Test engine	GEOSS Provider, GCI Operator
J	Register New Interop Arrangements	Add reference to standards or special arrangements in the GEOSS Standards Registry. (Co-developed by SIF and AIP)	SIR, CSR	GEOSS Provider, GCI Operator
K	Execute Processing Service	Discover, bind, and orchestrate a processing service, to produce new derivative data resources	CSR	# GEOSS Integrator # GEOSS User # GEOSS Provider
L	Semantic Mediation Use Case	Use Case for performing semantic mediation among disparate vocabularies for the purpose of GEOSS resource discovery	CSR, Clearinghouse, Portal	GEOSS Provider, GEOSS User, GEOSS Integrator
M	Semantic Enabled Search	This use case describes the conditions and steps for portals and application clients to support the GEOSS user in searching for resources of interest via a combined use of GEOSS Clearinghouses (or Community Catalogs) and Ontology Engines.	CSR, Clearinghouse, Portal, Broker	GEOSS Provider, GEOSS User, GEOSS Integrator
N	Develop Data Sharing Network	Discover GEOSS resources, establish federation “contract” between them to assemble and publish a larger-scale system resource.	CSR, SIR	#GEOSS Provider #GEOSS Integrator
O	Share Best Practices	Share Best Practices for participating in GEOSS and addressing SBA’s in the Best Practices Wiki (BPW)	BPW	# GEOSS User # GEOSS Integrator # GEOSS Provider
