04.12.2008: JSON Rules

Nowadays, Internet applications are on a large scale Rich Internet Applications (RIAs). Traditional RIA’s development does not always meet the requirements of novel applications. One possible solution is to enrich RIAs with rule-based reasoning. We present a JSON based rule language and its JavaScript?-based rule engine towards providing Web 2.0 applications with rule-based inference capabilities. While the rule engine is enough general, its main purpose is to execute production rules and Event-Condition-Action rules related to the web page DOM processing. This way the user’s browsing experience will be enriched with the ability to modify on the fly the DOM of the current document as well as the browser user interface (Firefox).

13.11.2008: Generating User Interfaces for Service Compositions

I am going to summarize my work at SAP Research and the current stage of my master's thesis, which evolved out of that.

At SAP I worked on the Internet of Services project, which develops software for the brokerage of value-added services. For these services to be used by end users graphical user interfaces are needed. Thus, I investigated how those can be generated automatically focusing especially on composed services. My approach uses an abstract user interface description language to enable service providers to specify semantics of the user interfaces for their services. When these services are then composed into new services, a combined user interface can be generated automatically.

The approach is validated through a prototype based on various Oryx components and open standards like XForms, BPEL and BPMN.

29.10.2008: Conversations in REST - Accessing several resources in an atomic context

The world wide web gained popularity as the platform of future applications. Burton Group Inc analysts predict REST to catch up with SOA within the next five to ten years [1]. While services exposing data and real world items as resources on the web are already well elaborated and understood, REST implementations still lack means by which one can include several operations of resources within an atomic context. [2]

During my recent work at SAP Research, I examined possibilities to leverage HTTP, supporting Conversations -- an atomic context spanning multiple interactions with explicit resources over the course of several operations (requests). The proposed solution uses a concept similar to reserved checkouts [3], where resources are bound to a Conversation identifier modeled as a resource on its own. All operations to resources bound to the same Conversation can be carried out completely or not at all (atomically).

I intend to write my master's thesis about this topic and sincerely invite you to listen to a presentation about the details as well as providing me with valuable feedback.
