"沟通成就一切、互动创造价值".面对无处不在的网络化交互,实现"互联网+"应用的创新价值服务,其关键在于如何通过支撑供-需交互的语义互操作技术,实现多样化涉众需求制导的业务协作以及面向软件模型资源的服务供给侧可互操作构造,以化解云计算中深层Web服务资源的"信息孤岛"难题.该文从软件服务工程的角度,探索了从模型驱动架构MDA到模型交互驱动架构MiDA的演进;提出并论述了MiDA的三大内核技术,即RGPS需求元描述、服务供给侧的O-RGPS构造元模型以及互操作性元模型框架标准系列MFI(O-RGPS),揭示了三者之间多个"含意三角形"模式联动的基本过程以及虚实互动的软件模型互操作过程,阐明了MiDA与MDA的兼容性.最后,论述了作者负责研制的、面向模型语义互操作性治理与管理的ISO国际标准系列,对其中"过程模型注册元模型"的语义互操作性能力进行了分析与度量.上述理论和方法有助于提升我国"互联网+"企业在云计算与大数据关联分析方面的创新服务能力,可满足企业的动态业务协作以及面向多租户的个性化服务推荐需求,能够为供-需互动提供可互操作的服务供给侧结构,具有重要的实际应用价值.

‘Communication achieves all,and interaction creates value.＇To realize innovative value services of‘Internet plus＇ applications in the context where networking interaction exists everywhere,the supply-demand interaction and its semantic interoperability techniques become the golden key to facilitate on-demand business collaboration,construct‘Supply-Side＇services oriented towards software models,and finally resolve the ‘Information Islands＇ crisis of deep Web resources（e.g.services）in Cloud Computing.From the perspective of service-oriented software engineering,this paper explores the nature that Model Driven Architecture（MDA）evolves into Model-interaction Driven Architecture（MiDA）,and proposes three core techniques in MiDA,including RGPS requirements metamodel framework,O-RGPS construction metamodel for‘Supply-Side＇services,and their international standardization on Metadmodel framework forinterpretability,i.e.MFI（O-RGPS）.In detail,RGPS requirements metamodel framework intends to characterize diverse and personalized service requirements at different levels of granularity,and then it can support requirements directed interaction between models.O-RGPS construction metamodel can facilitate domain knowledge or topic mining for the subjects of‘Supply-Side＇service.In addition,it introduces the semantics enhanced ontology and metamodeling approach to construct an interoperable structure for‘Supply-Side＇services,in terms of RGPS annotations,semantic annotations and inherent associations between them.Considering MFI（O-RGPS）,it provides a series of standard registration metamodels for different types of models,including ontology,role and goal models,process models,and service models.With these metamodels,semantic interoperation between heterogeneous models can be conducted by sharing registration information in a unified way.Furthermore,this paper reveals two types of relationships between these three core techniques in MiDA.One is the basic relationships derived from the joint action of multiple meaning triangle patterns;the other is the virtual-reality interaction and interoperation between software models.Moreover,the authors conclude that as the evolution of MDA,MiDA is compatible with MDA.In the end,this paper discusses the ISO international standard series named MFI（O-RGPS）,which was proposed by the authors and aims at semantic interoperability governance and management of software models.In order to evaluate the interoperability capability of MFI（O-RGPS）standards,this paper takes MFI-5,Metamodel for process model registration,as an example and proposes a method to measure the semantic interoperability capability of MFI-5 for heterogeneous business process models.More specifically,we define the mappings from specified process modeling languages or specifications（e.g.BPEL and EPC）to the metamodel in MFI-5 to register administrative information and selected metadata of process models.Based on these mapping rules,for each specific process modeling language,the proportion of mapped elements in the total number of elements can be used to quantify the interoperability degree of MFI-5 to the process models described with this modeling language.The results suggest that our proposed interoperability theory and method can enhance the innovation and service ability of‘Internet plus＇ enterprises in cloud computing and big data analysis,and satisfy the requirements for both dynamic business collaboration across enterprises and personalized services recommendation oriented towards multiple tenants.This implies that our method can provide interoperable construction for‘Supply-Side＇services to support supply-demand interaction in practice.
