While today more than ten years later the building blocks (1) resource-oriented rest infrastructure, (2) Web APIs, and (3) Linked Data are in place, the envisioned intelligent agents have not landed yet. In this paper, we explain why capturing functionality is the connection between those three building blocks, and introduce the functional API description format RESTdesc that creates this bridge between hypermedia APIs and the Semantic Web. Rather than adding yet another component to the Semantic Web stack, RESTdesc offers instead concise descriptions that reuse existing vocabularies to guide hypermedia-driven agents. Its versatile capabilities are illustrated by a real-life agent use case for Web browsers wherein we demonstrate that RESTdesc functional descriptions are capable of fulfilling the promise of autonomous agents on the Web.","PeriodicalId":268294,"journal":{"name":"International Workshop on RESTful Design","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114978602","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

REST has proven to be a viable solution for such large-scale information systems. It provides a set of architectural constraints that, when applied as a whole, result in benefits in terms of loose coupling, maintainability, evolvability, and scalability. Unfortunately, some of REST's constraints such as the ones that demand self-descriptive messages or require the use of hypermedia as the engine of application state are rarely implemented correctly. This results in tightly coupled and thus brittle systems. To solve these and other issues, we present JSON-LD, a community effort to standardize a media type targeted to machine-to-machine communication with inherent hypermedia support and rich semantics. Since JSON-LD is 100% compatible with traditional JSON, developers can continue to use their existing tools and libraries. As we show in the paper, JSON-LD can be used to build truly RESTful services that, at the same time, integrate the exposed data into the Semantic Web. The required additional design costs are significantly outweighed by the achievable benefits in terms of loose coupling, evolvability, scalability, self-descriptiveness, and maintainability.","PeriodicalId":268294,"journal":{"name":"International Workshop on RESTful Design","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126271903","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The latter are the focus of the first contribution in this paper, where we propose a simple peer-to-peer solution adapted to the needs of RESTful services. The second contribution, is the combination of the data staging mechanism with a simple service deployment mechanism, that is designed to allow applications developed for the command-line to function as (RESTful) services without modification or (in some cases) recompilation. Thus, the aim of this paper is to describe the design and implementation of: (i) a peer-to-peer data-staging mechanism, that is itself RESTful, and (ii) a service deployment mechanism, also following REST design principles, which together form the Universal Distributed Data-flows framework, for the support of data-intensive (RESTful) workflows. We evaluate the framework by means of an engineering workflow developed for multi-disciplinary design optimization. The workflow itself is specified in Taverna, which is a conventional centralized data-staging enactment system. However, by virtue of the underlying services and staging mechanisms described here, the resulting enactment is peer-to-peer (for data), which furthermore permits asynchronous staging, with potential benefits for network utilization and end-to-end execution time.","PeriodicalId":268294,"journal":{"name":"International Workshop on RESTful Design","volume":"160 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130045989","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the crucial parts when adding a REST interface to an existing application is creating an appropriate resource model. Utilizing any available model of the legacy application can accelerate development significantly because existing domain knowledge, data, and business process implementations can be reused. Despite the maturity of the architectural style, there is still little record of creating a resource model from existing object-oriented applications. This article presents a lightweight modeling process: First we harvest an existing object model for resource candidates, afterwards the resulting model is enhanced incrementally until a suitable resource model emerges. The process is illustrated by a case study that highlights interesting challenges, such as a comprehensive domain model and long running processes, as well as pragmatic solutions for these challenges. The paper demonstrates that it is feasible to add a RESTful interface to a legacy application even in a process rich environment.","PeriodicalId":268294,"journal":{"name":"International Workshop on RESTful Design","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133361359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We say \"so-called\" because in reality, most of these services are not very RESTful. Those active in the REST community know well where these interfaces fail to meet REST principles, however, true understanding remains only in this relatively small community. Unfortunately, the result is a set of interfaces that are ultimately limited in their use, and the deficiencies are not usually recognized until it is too late to make the necessary changes. Our experience has shown that individuals are not being deliberately neglectful, rather, they simply do not know what they do not know. Everyone thinks they \"get REST\", after all, using HTTP to move XML or JSON payloads over the network is very simple. We have found that most individuals begin to understand the nuances of REST when they are explained and they almost always ask for resources that further explain these concepts. Certainly, materials are available, however the best ones are rather substantial in size lessening the chance that many people will read them.\u0000 In this paper we take a fresh approach to explaining the core principles of REST, by describing a World Wide Web that fails to meet these tenets. We look at each key element, resource orientation, the uniform interface, media types and hyperlinking, and imagine the consequences of not abiding by the REST architectural style on the end user or tools developer of the Web. We then do a similar analysis in the context of Web services and programmatic consumers, reexamining each REST characteristic, describing common mistakes and suggesting improvements. We have found that in discussions, the analogy of the World Wide Web has been very effective at explaining REST.","PeriodicalId":268294,"journal":{"name":"International Workshop on RESTful Design","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131461828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The binding of the disjunct components of this architecture creates security issues, such as the centralized authorization techniques respecting the independence of the underlying entities. This results in the question how authorization is performed respecting the flexibility of REST without any knowledge about the underlying resources. Nevertheless, possible knowledge about these resources should enable the authorization workflow to offer finer-granular permissions on substructures of the resources. With our new approach - we named Hecate- we offer a framework to assure simplified handling while keeping the potentials and flexibility of REST. We have designed an architecture based on XML with a flexible authorization mechanism on the one hand and optional resource-awareness on the other hand. The flexibility within the authorization work-flow bases on permission sets respecting the HTTP-verbs. Additional in-depth knowledge of the entity optionally extends these permissions with resource-aware filters. Hecate offers not only great benefits because of its flexibility, but also because of the optional extensibility proved within the two reference implementations. With Hecate, we show that a centralized authorization mechanism combining independence and optional resource-based filtering extends the flexibility of REST rather than restricting it.","PeriodicalId":268294,"journal":{"name":"International Workshop on RESTful Design","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120983193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
