14. XNAT 1.7: Scalability Port from embedded database to Postgres Port from embedded database to Postgres Load balance web server and database server. Load balance web server and database server. Distributed file systems (iRODS, S3, etc) Distributed file systems (iRODS, S3, etc)

15. XNAT 1.7: Other stuff? Any other high priority features? Any other high priority features?

16. XNAT 2.0 User experience reboot User experience reboot Core internals reboot Core internals reboot Search engine reboot Search engine reboot Statistics engine Statistics engine Reporting/charts/analytics Reporting/charts/analytics Integration & federation Integration & federation Expanded DICOM integration Expanded DICOM integration Rule engine (w/ notification and query services) Rule engine (w/ notification and query services)

17. XNAT 2.0: User interface reboot Focus group and survey results Focus group and survey results – Make it faster! – Don’t break the good stuff! – It can do that? I had no idea! – Why’s it so ugly? – Why are my pipelines always broken? – Make it simpler to X, where X is: Upload, download, search, browse, view, build, enter, … Upload, download, search, browse, view, build, enter, …

18. XNAT 2.0: User interface reboot Guiding principles: Guiding principles: – Make it faster – Make it simpler – Retain hierarchical navigation – Improve internal documentation – Use modern web technologies – Use a consistent toolkit – Use consistent design patterns – Make it cool

19. XNAT 2.0: User interface reboot Functional requirements doc at https://wiki.xnat.org/download/attachments /5016779/FRD+Final+-+Deliver.docx Functional requirements doc at https://wiki.xnat.org/download/attachments /5016779/FRD+Final+-+Deliver.docx Design preview at http://integrity.prevuu.com/p/xnat Design preview at http://integrity.prevuu.com/p/xnat

20. XNAT 2.0: Core internals reboot No decisions yet but considering: No decisions yet but considering: – Replacing Turbine – Replacing Restlets – Replacing Maven – Replacing XFT – Replacing Velocity

21. XNAT 2.0: Core internals reboot Nothing’s broken. So why go monkeying around with it? Nothing’s broken. So why go monkeying around with it? – We might not – Because there’s a steep learning curve – Long-term maintenance could get tricky – Some of it is getting pretty long in the tooth

22. XNAT 2.0: Search engine reboot Join logic needs improvement Join logic needs improvement Search interface needs massive improvement Search interface needs massive improvement Search by scan parameters Search by scan parameters

23. XNAT 2.0: Statistics engine https://synapse.sagebase.org/#Synapse:syn150935

24. XNAT 2.0: Statistics engine Step 1: R interface to XNAT via REST API Step 1: R interface to XNAT via REST API – Should be pretty straightforward as we’ve already done it in python, java, matlab,… Step 2: Embed R in XNAT itself Step 2: Embed R in XNAT itself – Standard script library – User supplied script library – “Include” statements pull data based on current criteria – Executes in sandbox

25. XNAT 2.0: Reporting

26. Standard suite of charts that users can embed in reports. Standard suite of charts that users can embed in reports. Reports can be dynamic or snapshots. Reports can be dynamic or snapshots. Stats engine can drive chart population. Stats engine can drive chart population.

27. XNAT 2.0: Integration & federation Federate multiple XNATs to provide a single unified view. Federate multiple XNATs to provide a single unified view. Integrate XNAT with other databases (I2B2, REDCap, etc) Integrate XNAT with other databases (I2B2, REDCap, etc) Requires single sign-on and federated identity providers. Requires single sign-on and federated identity providers. Requires better standardization of common data elements. Requires better standardization of common data elements.

28. XNAT 2.0: DICOM Enable C-FIND, C-GET, C-MOVE, C-WHATEVER Enable C-FIND, C-GET, C-MOVE, C-WHATEVER Module to pull and anonymize studies is currently in development Module to pull and anonymize studies is currently in development Standard pipeline step to generate secondary images & structured reports Standard pipeline step to generate secondary images & structured reports Early Adopters Program to generate requirements and test.
