If you can see this paragraph, your browser is most likely not supporting CSS, an emerging technology for separating layout and content in (X)HTML pages, allowing for a more structured markup in hypertext documents. To learn more about the advantages visit a brilliant (and funny) presentation by Bill Merikallio and Adam Pratt explaining the pitfalls of conventional, table-based design for HTML. In particular, CSS allows web sites not only to look good, but to also be accessible for non-conventional user agents, such as search machine robots (use by, e.g., Google), PDA-based user agents, or user agents for people with disabilities. For more information on designing accessible web pages, see the Web Accessibility Initiative (WAI) at the W3C.

Computational Treatment of Temporal Notions (CTTN)

The CTTN-system is a computer program which provides advanced processing of temporal notions. The basic data structures of the CTTN-system are time points, crisp and fuzzy time intervals, labelled partitionings of the time line, durations, and calendar systems. The labelled partitionings are used to model periodic temporal notions, quite regular ones like years, months etc., partially regular ones like timetables, but also very irregular ones like, for example, dates of a conference series. These data structures can be used in the temporal specication language GeTS (GeoTemporal Specications).

GeTS is a functional specification and programming language with a number of built-in constructs for specifying customized temporal notions. CTTN is implemented as a Web server and as a C++ library.

Local Data Stream Management System (L-DSMS)

L-DSMS is a general system for configuring and (locally) executing networks of processing nodes for data streams. Each such node receives data from one or several data sources, processes them in a certain way, and delivers the processed data to one or more data drains. A data drain can be the data source for the next processing node in the network, or it can be the end application in the whole processing chain. One of the components of L-DSMS is the SPEX XML filtering system. It processes XPath queries on a stream of XML data and can be used to extract interesting information from XML streams.

GeoDataServer is an application for processing dynamic geoinformation data (e.g. traffic information). The data comes from different sources (e.g. RDS-TMC capable FM receivers) and is processed in several steps and then delivered to enduser systems (e.g. graphical visualization systems).

Ontology based Traffic Network (OTN)

The Ontology based Traffic Network (OTN) deals with the most important aspects of traffic networks, transportation and locomotion in general. It is based on the Geographic Data File format (GDF) which is available as the ISO standard 14825 and is currently at version 4.0.

For the purpose of transforming OTN data to SVG, i.e. displaying data in a SVG-enabled web browser, we provide the transformation ontology OTN2SVG.
