The project aims to experiment with international real-time exchange of data using publication/subscription (pub/sub) protocols in combination with a distributed storage of the original data along with a central, mirrored repository for easy access to the complete distributed data set. Additionally, the data will be discoverable using WIS Metadata. Thus, this project also assesses the advantages, disadvantages and usability of WMO Core Metadata Profile 1.3 complemented by the exposure of this data to commercial search engines. The latter being seen as an input to the further development of WIS 2.0 Metadata and the topic structure for the pub/sub messaging.
In this project, participating centers will make available their NetCDF data through the internet by using established technologies like HTTPS, FTP, or WebServices and provide discover, access, retrieve (DAR) Metadata in WMO Core Profile 1.3 to the Global Information System Center (GISC) Offenbach, either in XML-Format, through OAI, or through GISC Offenbach’s MetadataEditor.
GISC Offenbach will use the Metadata to access and collect the available NetCDF data. Either by Centers actively pushing the data to GISC Offenbach or by GISC Offenbach harvesting the data from Centers through the Internet.
Interested users will be able to request access and subscribe to the message brokers to receive notifications when new data will be available to be downloaded from the central repository.
