What is Software Resource?What is Software Resource?A software resource (SR) is, broadly speaking, any

cohesive collection of artifacts that solve a specific problem or set of problems encountered in the software development life cycle. SR is reusable artifact, it can be used to build new

software products and related products. A SR may be any work-products from the software

development lifecycle or software related activities.• requirements documents, models, source code files,

deployment descriptors, test cases or scripts, and so on.

Reuse Based Software Development (RBSD) and Software Resource.

44

The Software Resource Repository (SRR) is the

infrastructure that provides the software resources

management mechanism, such as publishing,

retrieving, classification, storage, feedback, evaluation.

Supporting software reuse.

Sharing resources among projects.

Software Resource Software Resource RepositoryRepository

Trust is the belief that the trustor has in the trustee willingness and capability to deliver a quality of service in a given context and in a given timeslot. [Chang 2005]

The Trusted Software Resource Repository (TSRR) is needed to provide mechanism to describe, collect, evaluate, classify and manage software resources’ trustworthiness, to support trust software development.

The Background of SRR for TrustieThe Background of SRR for Trustie

66

The Goal of TSRRThe Goal of TSRR

Provide software resource management mechanism and software resources sharing environment.

Provide software resources acquisition, organization and management on the Internet.

Provide mechanism to describe, collect, evaluate, classify and manage software resources’ trustworthiness, to support trust software development.

Typical Software Resources in TSRRTypical Software Resources in TSRR

Software components: A software component is an explicitly identifiable

software entity that has independent functionalities and can be deployed independently.

The component can be embedded in target systems in form of source code or binary code etc.

Software services: A kind of software entity that emerged in form of

running service that can be referenced or invoked by target systems, such as web services.

88

Software tools A kind of software entity , which can assist the

realization of tasks and actions of software developing, software running, software maintaining, software managing or software supporting etc.

Software architectures The software architecture is the structure or

structures of the system, which comprise software components, the externally visible properties of those components, and the relationships between them.

Main functions of TSRRMain functions of TSRR

Now, We have:Software resource publishing,

retrieval, classification, user management, statistics etc.

Support RAS specification for storing and managing resources.

Web Service’s QoS management subsystem can collect and measure Web Service’s QoS

Internet-based software resources search engine can harvest resources from Internet

The trust manager collects trust related evidences and evaluate the resources’ trustworthy level.

TSRR Application in ChinaTSRR Application in China

TSRR has been deployed in several Software Incubators which are established by National Hightech Program all over China , including Beijing, Shanghai, Changsha, Xi’an etc.

Also, there are several companies has installed TSRR to support their software development ,such as Digital China.

TSRR will contribute to OW2 in near futureTSRR will contribute to OW2 in near future

To set up a project on OW2 for TSRR The source code and the technical specification on

how to manage software resources will be opened on OW2 on Oct. 2009

Reuse existing OW2 projects: Jonas, JORM, JOTM, EasyBeans, xWiki , Orientware CCM, Celtix ESB, SpagoBI,

XPLUS, JassmineTo expand the application of TSRR, together to

push Jonas and other OW2 projects’ application in China

2222

What are we doing now…What are we doing now…

Published an English version of TSRR

To polish and optimize the source code of TSRR

The technical specification on how to manage software

resources is in progress

The platform migration is in progress, we have

successfully transplant the running platform and

database

2323

TSRR Plan for OW2 TSRR Plan for OW2

2009.10

To finish the migration of TSRR platform from commercial platform to open source platform

2010.2

•Apply to OW2 for setting up TSRR open source project

2010.3

•Set up dictionary of synonyms for TSRR Chinese version and English version •Furnish TSRR’s source code

•Make TSRR open source comprehensively on OW2
