+## Agenda
+
+## Site Updates
+
+### HZB
+
+DAPHNE4NFDI annual meeting - HZB hosting. Interesting discussions but not directly ICAT related. Otherwise nothing else to report.
+
+### ESRF
+
+Nothing new, progressing on technques. Working on including more processed data in the data portal.
+
+Working on OSCARS project on sample metadata in coming weeks and months. Discussion with Rolf next week on this topic.
+
+### ISIS
+
+Payara server upgrade to 6. Currently on staging. Out to production within the week hopefully.
+
+### DLS
+
+Had DataGateway & ICAT server & lucene upgrade released. Working on visit restore release now 
+
+## Component Updates
+
+### datagateway-download-api
+
+Single visit restore via queueing functionality.
+
+Rolf: IDS can sometimes perform badly when multiple restores at the same time. Add a parameter to limit the number of restores.
+Louise: there's some extra visit splitting functionality as well as DLS visits are very large
+
+### ICAT 7 schema changes
+
+Rolf says he may have a student who can work on icat.server issues.
+
+Rolf: STFC asked about Instrument startDate & endDate additions? Would be good if you could create a formal issue
+Louise: sure
+
+## AOB
+
+### icat.schema
+
+Investigation -> Dataset -> Datafile.
+
+More longer term experiments e.g. catalysis experiments, multiple hours. Lots of beamline measurements to observe sample changes. Want whole thing to be a Dataset, but might want to search for individual beamline measurements.
+
+Proposal: Datasets within Datasets?
+Would have a lot of consequences
+
+Louise: STFC facilities either only have 1 dataset (ISIS) or have datasets generally respresenting wrong things anyway (DLS - directories as datasets)
+
+Alex: single dataset, up to user to filter measurements within the dataset. Ideally keep ICAT as simple as possible
+
+Rolf: XAS measurement search, you might want to search an individual experiment as a measurement could be repeated many times within 
+
+Louise: complex, could have infinite nesting of datasets!
+
+Rolf: maybe not, you have control of your ingestion pipeline
+
+Alex: we have the opposite, we have many datasets that we want to group as one. Search is more of a problem but we think it's fine to e.g. search by technique etc. and rely on user to search files for specific measurements
+
+Louise: we probably need time to think about this offline
+
+Rolf: can discuss at next F2F?
+
+### Next F2F?
+
+Louise: we'll have to discuss with with our GL
+
+Kevin: yes, will need to think of when/who will host
+
+Kevin: sometimes we tag these on to other events - does anyone have ideas for this?
+
+Louise: how about we think about this offline with our institutions and discuss more concretely next time? maybe send out polls after that
+
+Rolf: can't attend the next 2 collab meetings
+
+### Next meeting
+
+24th April - week of Easter Monday
+
+Rolf: exactly why I can't go!
+
+Louise: well April is always hard, in between week before/after Easter & school holidays which may/may not overlap struggle to get everyone to attend anyway
