Dear XML community,
An enhanced commercial version of the proven GMD-IPSI XQL engine technology is now available - the Infonyte XQL Suite. XQL is a query language that uses XML as a data model, syntactically very similar to XSL patterns.
The Infonyte XQL Suite includes the complete functionality of the GMD-IPSI XQL Engine, plus bugfixes and speedups. Exciting new features have been added, e.g. multidocument queries, database joins, and navigation to documents via http. These unique features make the Infonyte XQL Suite a powerful and robust framework for XML based information brokering.
The Infonyte XQL Suite is distributed by GMD-IPSI's spin-off company GLOBIT - Global Information Technolgies GmbH. Along with the commercial distribution of the Infonyte XQL Suite, GLOBIT offers professional support, continuous maintainance, updates, training, and consulting.
For your convenience, find attached a more detailed description of the Infonyte XQL Suite, contact information, and some background information about GLOBIT. Please do not hesitate to contact GLOBIT (email@example.com) for further information.
Kind regards, GLOBIT's Infonyte Team
1. Product Description The Infonyte XQL Suite provides a comprehensive, lightweight solution for querying and storing large, distributed XML documents. It is based on two major components, a persistent implementation of the W3C DOM (Document Object Model) API and a web-aware query engine for the XQL language. The lightweight implementation requires only an off-the-shelf Java runtime environment. Having a remarkably small footprint for memory, storage, and CPU, it is well suited for distributed applications which require queryable document/data repositories. Likewise, it can serve as a solid base for CD-ROM products. With its integrated support for HTTP and URL, the Infonyte XQL suite also enables the generation of scalable, multi-user server applications built on Javasoft's Servlet technology. A particular strength of Infonyte XQL server applications is the support for seamless integration of existing web information services into your value added information products. The Infonyte XQL Suite originates from a research project at GMD-IPSI, the Institute for Integrated Publication and Information Systems of the German National Research Center for Information Technology. GMD-IPSI's XQL Engine and PDOM incorporate consolidated concepts from many years of leading edge research and development in the fields of federated databases and document management systems, and have been in a number of real life applications. With the Infonyte XQL Suite, GLOBIT offers an enhanced and stabilized version of the XQL Engine and the PDOM for commercial use. GMD-IPSI's research protoype continues to be available for non-commercial use and evaluation at http://xml.darmstadt.gmd.de/xql/. 1.1 The XQL Query Engine Component XQL is a query language for XML. It is very similar to XSL Patterns extended by querying features. XQL expressions are easy to type, can easily be parsed, and can be used in a variety of software environments, e.g., as part of a URL, in XML or HTML attributes, or in programming language strings. The Infonyte XQL Query Engine implements the complete XQL W3C-QL'98 workshop paper syntax version of XQL. Without trading the simplicity of XQL, it supports in addition: - Multi document queries - Navigational Web queries on HTML documents - Return operators and sequence operators (Proposed extensions to XQL) - database join functionality - User definable XQL functions (extensions) The implementation realizes a robust and efficient mix of indexing and query optimization techniques. This results in leading edge performance, especially for structurally complex queries. The engine can be used on top of any W3C compliant DOM implementation. This allows for seamless and simple embedding of XQL support into your applications and services. 1.2 The PDOM component The Infonyte Persistent Document Object Model (PDOM) implements the full W3C DOM API. It is specifically tuned to exploit the Infonyte XQL engine's optimization capabilities. Persistency is achieved by indexed, binary files. Documents are parsed once and stored in binary form, accessible to DOM operations without the overhead of parsing them first. A self-optimizing cache architecture further increases performance. This approach scales very well beyond the limitations of main memory. Thereby it forms a lightweight, flexible and often more efficient alternative to costly and heavyweight DBMS based solutions. 2.
