ICAT Integration at DLS. Alun Ashton
What were the requirements? • Integrate with current business system • Collect Data and Metadata relating to a proposal • Security • Long term storage of data • (Multi?) Institutional repository • Searchable Metadata • Potentially extendable with future e-science infrastructure • Scalable
What were the restrictions? • Only relies on Beamline Network. • Must not prevent scientist collecting data. • Data is collected by putting files onto a UNIX file system. • Use e-Science research output. • Interest, vision, priorities and finances.

What goes into the ICAT/Ikitten • Who • When • Where • ‘what’ • Abstract • Visit • Triggers I think moves the data to the iKitten DLS ICAT DUO Desk IKitten
What does the GDA read from the IKitten • Metadata read only • Fedid – the GDA knows the users Fedid and asks the DB for the current visit for that user, used for setting up data paths. • Instrument, abstract Data / metadata IKitten GDA
Role Based access and application sharing. • Definable access • Definable role • If this is not right…
What does the GDA write out? • GDA does not currently write a NeXus file, • Detector files and anything….. • Currently implemented only on MX beamlines Nexus & Data GDA
‘GDA’ needs to initiate next step • In the MX GDA whenever an image file is created it runs a script • Bash script creates an XML file as input to DArc • The GDA can produce a script itself but no beamlines currently do today… maybe next week? Nexus & Data GDA
DArc DArc Watches a directory • Python Based EDNA • Server that checks <>5s • http://www.edna-site.org Initiates storaged Copies a filelist To a location Converts file to XML Ingest format Runs XML ingest Success? Moves XML to A log
The XML file, minimum! <?xml version="1.0" ?><icat version="1.0 RC6" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="icatXSD.xsd"> <study> <investigation> <inv_number>MX307</inv_number> <visit_id>MX307-27</visit_id> <instrument>i04</instrument> <title>dont need it</title> <inv_type>experiment</inv_type> <dataset> <name>icr/fernando</name> <dataset_type>EXPERIMENT_RAW</dataset_type> <description>unknown</description> <datafile> <name>FG2_3_MS_3_154.img</name> <location>srb://srb-mcat-i18.esc.rl.ac.uk:5518/dls-2/i04/data/data/2009/mx307-27/icr/fernando/FG2_3_MS_3_154.img</location> <description>unknown</description> <datafile_version>1.0</datafile_version> <datafile_create_time>2009-08-11T02:58:21</datafile_create_time> <datafile_modify_time>2009-08-11T02:58:21</datafile_modify_time> </datafile> </dataset>
What is our status? • https://dataportal.diamond.ac.uk
Viewing and choosing the Metatdata Relation to NeXus
By the by…https://ispyb.diamond.ac.uk • Did try a view, now use a script ISPyB DLS ICAT DUO Desk IKitten
ICAT Archive Generic ISPyB LIMS Domain specific ISPyB and ICAT

Future Work • Use it!!! • Portal and API integration into in house tools • Sample information from user office (top level information about the sample, and ISPyB (the instance of the sample). • Internal ICAT. • Reduced data and richer metadata. • Archive old data
