This document describes YAMCAT, an open source catalog for managing spatial metadata and facilitating collaboration on projects. YAMCAT allows users to search for and share geospatial metadata, download geospatial data, and preview data layers using WMS. It includes forms for adding and editing metadata according to ISO 19139 standards and can export metadata to the GeoNetwork catalog. YAMCAT requires a web server with PHP and mySQL and optionally MapServer, and aims to support collaboration and data sharing for scientific projects.

The BigDataEurope project aims to empower mobility management with big data. It has developed a modular platform that allows end-users to easily deploy functionality in their own systems using Docker containers. The platform is being tested through 7 pilot projects aligned with European societal challenges related to data-driven solutions. One pilot focuses on transport in Thessaloniki, Greece, using GPS, Bluetooth, and other probe data to improve map matching and mobility pattern recognition and forecasting to better manage traffic. The project coordinators are available for any questions.

Europeana Newspapers

The document discusses Optical Layout Recognition (OLR) to convert scanned newspaper pages into structured digital files. It describes CCS's role in providing OLR technology and services to structure over 2 million newspaper pages from 5 European library partners. The general OLR workflow involves scanning, layout analysis to identify text blocks and zones, OCR, and quality assurance. CCS will analyze page layouts to recognize elements like articles, headlines, images and classify page types. Libraries can perform final quality assurance checking on the structured output, which is packaged in METS and ALTO formats for preservation and improved search and access capabilities.

Ibm infosphere mgarren

mgarren

IBM InfoSphere Streams is a scalable stream processing platform that can be used to build real-time intelligent transportation systems. It allows processing of both structured and unstructured data streams from multiple sensors in real-time. The stream processing is done through a data flow graph of streaming data objects and processing elements using the SPADE processing engine. A pilot project in Stockholm used InfoSphere Streams to monitor current traffic by comparing real-time GPS data to historical data to estimate travel times and compute shortest paths, providing visualizations to end users. The system was able to process over 1,000 GPS readings per second from various vehicles.

Making Wikidata fit as a Linking Hub for Knowledge Organization Systems

Joachim Neubert

Wikidata can serve as a linking hub for knowledge organization systems by using its new "mapping relation type" qualifier (P4390) to optionally qualify external property relations with a mapping type like exactMatch, closeMatch, or narrowMatch. This qualifier allows tracking its usage by relation type and external ID properties. The qualifier aims to improve Wikidata's role as a hub for linking different knowledge organization systems.

Open Source in Practice at SNS Bank

Eric D. Schabell

SNS Bank has transitioned to using open source software over time, starting in 2004 when they primarily used proprietary software. They have implemented a "Straight Through Processing" strategy using the open source JBoss application stack and jBPM business process management software. An initial project implemented savings product purchase processes in jBPM, which are now available online. Further projects expanded the number of products and implemented additional bank service processes in jBPM. SNS Bank continues working to migrate systems to newer open source versions and integrate development tools to improve their use of open source software for business process management.
