- 10. ● 1) Describe API contract ○ endpoints, resources, HTTP methods, representations ○ enable the generation of: ■ client SDKs ■ server skeletons ■ test suites ■ mock servers ● 2) Implement API ○ wrap regular applications written with classic languages ○ compose lower-level APIs into higher-level APIs ○ integration purpose at web scale ● 3) Operate API ○ provide the infrastructure to deliver the API ○ access to data and services Maturity levels of API Languages Lower level languages API delivery network
- 11. ● Swagger (2.0) ○ acquisition by SmartBear from Reverb ○ tooling has been upgraded ○ leader in term of community adoption ○ specification contributed to Linux Foundation ● RAML (1.0 RC) ○ added libraries, overlays, improved examples, security schemas, annotations, and data-typing ● API Blueprint (1A9) ○ support for MSON and URI template added ● Will all three languages be able to converge? What changed in 2015?
- 12. Languages are Abstraction Layers Hardware Assembly languages System languages Application languages Web API languages software level, drivers NASM / TASM OS level, high performance C / C++ / C# / Go productivity, portability, business logic Java / PHP / Visual Basic web scale, interoperability, integration, DSLs Swagger / RAML / API Blueprint lowest level, machine code x86 / CISC / RISC / etc. 1st generation 2nd generation 3rd generation 4th generation 3rd generation
- 13. ● 50% of classic languages at the top ● Java rising to 1st place on its 20 years anniversary. ● Cobol and Assembly in the top 20 and rising ● New languages emerging (Swift, Dart, Go) ● An API language in this list? Source: TIOBE index Top programming languages 2015
