Features• RESTful

– 3rd level Richardson Maturity Model RESTful APIs

– Full Hypermedia As The Engine of Application State (HATEOAS)

• Authentication– Restrict access to selected resources

• Search– Search functionality (Lucene) mapped to

resources of your choice• Deploy ready

– Maven project ready to deploy to a container of your choice

• Code Generation– Automated code generation from

multi-modal requirements (English text, UML diagrams, storyboards)

• External web services– Call 3rd party REST web services– Create mashups of web services

• Database– Generate the schema and database

• Authorization– Enable attribute based access control

(ABAC) – coming soon


12

Working with S-CASE• Create requirements• Create service mashups• Generate code• Deploy WAR

• RESTReviews– 2100 LoC in Java– 15 mins from scratch– 0 bugs

There’s more...• Analyze natural language (NLP)• Find open source projects

– Using existing indices (MARKOS, Agora)• Index and query (in English) over your projects• Publish your own services

– YouREST service catalog, SAT tool, automatic• Perceived reliability, maintainability & code metrics of the service

– Exceeds NASA standards• Expand the platform

– 2D MDE – expandable code generation
