All the services provided to the museums take advantage of the cloud. For instance the interactive installation does not need to have servers that hosts locally the collections and educational material that is used but it connects directly to the infrastructure that runs over the cloud

agricultural research(+) content• publications, theses, reports, other grey literature• educational material and content, courseware• primary data, such as measurements & observations – structured, e.g. datasets as tables – digitized, e.g. images, videos• secondary data, such as processed elaborations – e.g. dendrograms, pie charts, models• provenance information, incl. authors, their organizations and projects• experimental protocols & methods• social data, tags, ratings, etc.• …

data infrastructure for agriculture• aim is: promoting data sharing and consumption related to any research activity aimed at improving productivity and quality of crops ICT for computing, connectivity, storage, instrumentation
we actually share metadata Author SubjectID Title Publisher Date Catalog
metadata aggregations• concerns viewing merged collections of metadata records from different sources• useful: when access to specific supersets or subsets of networked collections – records actually stored at aggregator – or queries distributed at virtually aggregated collections 15
typically look like this 16 Ternier et al., 2010
metadata aggregation tools More than a harvester: Validation Service Repository Software Registry Service Harvester Powered by 17
workflows with commonalitiesHarvesting Validating Transforming OAI target - XMLs Storing Indexing XMLs Automatic De - duplication metadata Triplification service generation
even when machinery exists there are problems• hardware maintenance• technical support• interoperability limitations – no APIs for the dissemination of data across systems• hardware costs
the cloud approach Students Academics Researchers
what can be hosted on the cloud• Data storage & management tools – APIs for content dissemination in large networks• Processing & visualisation tools• Metadata aggregation infra• Search engines and apps for institutions or communities
what data providers need… only a browser and internet connection
comparing costs for hosting datamanagement tool at own site and cloudCloud Hosting at institution•cloud hosting = 20 euros/month •1 server+monitor+ups = 1200 euros•set up effort = 1hr •set up > 1 day effort or 100 euros•back up included •hardware maintenance effort = difficult to be defined but significant•Total for 5 years = 1200 euros •Total for 5 years = 1300 +personnel for hardware maintenance+ costs of unexpected HW breakdowns e.g. supplier, hard disk Costs of software support Costs of software support After 55years the HW should be After years the HW should be could be the same for both could be the same for both renewed/upgraded renewed/upgraded cases cases
