  1. Welcome to … Othmar Weber // Bayer Business Services // iRODS UGM 2019 Utrecht

  2. iRODS @ Bayer When? ▪ Introduced in 2014 What? ▪ Scientific data (images, genome, …) @ Who? ▪ Data scientists ▪ Data manager ▪ Data loader How much? ▪ Three department installations ▪ ~160 TB

  3. iRODS usage in genetic research Data Scientist Data Owner Data Manager I am mainly interested in my As a data owner I need to make To make sure that our data is research project. I need the sure that the access to the data well organizedI have compiled a data for my work. When I am is limited to the absolute list of metadata attributes that done I have to archive the raw minimum. If a patient retracts need to be attached to each and result data into iRODS and her/his consent I need to item. The rules differ from data tag it properly accourding our identify her/his data and make type and research type. sure that it gets deleted. rules. I don‘t like bureaucracy and For me data is handled like an Rules are needed to make data rules! asset. FAIR!

  4. Following the rules … On study type abc you Seriously??? need this list of attributes. On xyz you need that. By the way: they need to be recursive. I have also compiled a list for allowed values of certain attributes. Some also need to be verified to public ontologies. For certain file types I need attribute cdf attached … Finding: Creating rules is easier than complying to them!

  5. 1st approach: iRODS Metatool Users can use Excel to create input for the metatool Seriously??? Rules are defined in XML file Metadata can be attached via the metatool which checks the rules

  6. Next iteration …

  7. Product vision For Scientists who need to ensure compliance with data security/privacy, and find information in iRODS, Rodinaut is a web application that enables viewing and managing metadata. Unlike the existing command-line tool, our product is self-explaining, easy and fast to use and improves user experience with iRODS.

  8. iRODS Metadata mangement made easy… Intuitive & visual metadata management ▪ Controlled vocabulary via template definitions ▪ Supporting lists and ontology lookups Using standard iRODS features ▪ access rights ▪ No change of iRODS code Concept of metadata inheritance ▪ Asynchronous with locking Based on Open Source technology ▪ Docker ▪ ReactJS (Frontend) ▪ Java Spring Boot (Backend) + Jargon

  9. Live (?) Demo …

  10. Navigating the tree … Navigation via breadcrumbs

  11. Get to the Metadata Show Metadata

  12. Show metadata inheritance status Metadata Attribute / Value

  13. Editing Metadata Predefinedlist Required attribute based on tree Not required attributes can be removed

  14. Editing Metadata Attribute specific validation Ontology verification Add additional attributes

  15. Check metadata of subdir Inheritedfrom parent

  16. Break inheritance Inherited attributes are not editable Change inheritance to allow overwrite

  17. Break inheritance Attribute now changable Inheritance starts from here now

  18. Demo mode off …

  19. Behind the scenes Custom attribute to realize inheritance (pass_on_attribute) Sets the root of an inheritance Contains the name of the attribute that should be inherited Can be set multiple times for different attributes Setting on a child level means breaking the inheritance Background job to recursively apply the attributes to a tree Needed to avoid blocking the UI while large trees are processed Locks the tree where inheritance is performed (just for Rodinaut) Runs as service with the rights of the original user

  20. Work in progress … Metadata Search File Creation, Upload & Download Session handling bug requires daily restart Strong separation of user and system rights Better documentation of rules.xml, create XSD Better abstraction of infrastructure services (auth provider, ontology definition)

  21. Logout completed …
