The core ontologies are defined in OWL, while workflow templates, requests, and candidates are expressed in RDF. Many constraints are represented as RDF triples, others that are more complex are represented via Jena Rules.

We have integrated the Wings semantic workflow system with a variety of user interfaces, and submitted workflows with a variety of execution engines. WINGS assumes external catalogs of software components and datasets that can be accessed through services. This is an important feature, since scientific environments consist of distributed services to access the data and algorithms necessary for data analysis. Many collaborations are set up where each institution may contribute resources (data, instruments, computers, software) by making them available to others while being maintained by the institution. Data providers may provide services to access data sources. There can be many organizations playing the role of data providers, and as a result data may be accessible in various catalogs that are in distributed remote locations. Other organizations may provide algorithms, services, models, or implemented codes that can process data and can be used as components of workflows. Each provider maintains the resources they contribute. Therefore, the WINGS architecture is designed to interface with external data and component catalogs.

In cases where privacy or off-line use are important, WINGS can submit workflows in a scripted format for execution in the local host. In cases where scale is important, WINGS can submit workflows to Pegasus or OODT which will manage their execution in shared distributed resources in an efficient and scalable manner. Pegasus selects computational resources, optimizes the workflow structure, submits the workflow for execution, monitors its progress, and resolves possible failures. WINGS has also been integrated with a variety of alternative execution engines, such as the System S engine for data stream processing and BPEL4WS engines.

We offer a WINGS sandbox where anyone can use WINGS with a simple set of workflows that we have developed for tutorial purposes. The Wings Semantic Workflow Reasoner runs in the background, the user interface is the Wings Web Portal, and the execution is done by Pegasus or OODT.

There are several Wings installations (ranging from older versions to newer versions) that contain workflows in diverse application areas, all of them require setting up an account to access:
