• #2: CONTROL ID: 1469340 TITLE: An Open Source Tool to Test Interoperability AUTHORS (FIRST NAME, LAST NAME): Luis E Bermudez1 INSTITUTIONS (ALL): 1. Open Geospatial Consortium, Rockville, MD, United States. ABSTRACT BODY: Scientists interact with information at various levels from gathering of the raw observed data to accessing portrayed processed quality control data. Geoinformatics tools help scientist on the acquisition, storage, processing, dissemination and presentation of geospatial information. Most of the interactions occur in a distributed environment between software components that take the role of either client or server. The communication between components includes protocols, encodings of messages and managing of errors. Testing of these communication components is important to guarantee proper implementation of standards. The communication between clients and servers can be adhoc or follow standards. By following standards interoperability between components increase while reducing the time of developing new software. The Open Geospatial Consortium (OGC), not only coordinates the development of standards but also, within the Compliance Testing Program (CITE), provides a testing infrastructure to test clients and servers. The OGC Web-based Test Engine Facility, based on TEAM Engine, allows developers to test Web services and clients for correct implementation of OGC standards. TEAM Engine is a JAVA open source facility, available at Sourceforge that can be run via command line, deployed in a web servlet container or integrated in developer’s environment via MAVEN. The TEAM Engine uses the Compliance Test Language (CTL) and TestNG to test HTTP requests, SOAP services and XML instances against Schemas and Schematron based assertions of any type of web service, not only OGC services. For example, the OGC Web Feature Service (WFS) 1.0.0 test has more than 400 test assertions. Some of these assertions includes conformance of HTTP responses, conformance of GML-encoded data; proper values for elements and attributes in the XML; and, correct error responses. This presentation will provide an overview of TEAM Engine, introduction of how to test via the OGC Testing web site and description of performing local tests. It will also provide information about how to participate in the open source code development of TEAM Engine. http://cite.opengeospatial.org/ KEYWORDS: [9300] GEOGRAPHIC LOCATION, [1976] INFORMATICS / Software tools and services, [1908] INFORMATICS / Cyberinfrastructure, [1982] INFORMATICS / Standards.
• #5: Scientist interact with raw data that can be in different formats and shapes
• #6: They can also publish data
• #7: How good is there communication, Do they really interoperate (access, process, use). Is the interface that they are using well known?
• #8: How good is there communication, Do they really interoperate (access, process, use). Is the interface that they are using well known?
• #13: Global forum of developers and users to advance geospatial standards
• #14: The Compliance Program deals with three main activities: Oversee Compliance Testing activities with SWG and software developers to improve the testing tools and the tests Manage the process for certification of software products Coordinate plugfest activities, where by via short term interoperability integration activities the test and the standards are advanced.
• #15: Requirements = tests = passes predefined testable assertions
• #16: Software implementations can get OGC certified. OGC certified implementations get a badge, that has the information of the organization, the software product and the standards that the product has implemented.
• #17: Organization seeking to buy or use software they can search in the OGC database and check what implementations have been certified
• #18: Implementers get more business and can easier promote their product
• #19: Software companies that want to get certified need to follow the OGC compliance procedure. They go to the online testing engine facility. If the results are successful then they fill up a test result form that it gets process by OGC staff. Depending on the membership level, the company needs to pay a license fee to use the OGC certification branding in their marketing materials.
• #20: Super passing = supervision– evalutaion + test
• #22: OGC has released the Guide for Software Acquisition White paper, that will help those acquiring software to put the correct wording in their procurement documents.
• #24: Open source in guthub
• #26: When the user logins to TEAM Engine he can select the test that he wants to perform and provide a description for that testing session.
• #27: TEAM engine will open various windows. One that can ask for more input. For example endpoint of the server and a console that gives realtime feedback on the progress of the test.
• #28: Finally the user gets the summary of the results
• #31: Use case
• #34: Resources:datasets, catalogs, vocabularies, information models, services, process models, repositories, etc. Tupes: (resources, people/organizations, publications, models, workflows, software, activities, etc.)
• #43: Data is a pan-european dataset of European Environment Agency – not yet publicly available - within a Framework Contract led by KU LEUVEN, where Epsilon Italia is a member of the team
