To be clear, Ole was only representing himself and not GN.The two main topics, which are somewhat intertwined, were: 1) how can we better understand and handle the concept of a domain when discussing data; and 2) how can we build systems that better enable us to search "for" data, not just search "in" data that we know exists?Some practical advice and general conclusions from Ole: Leverage what the Library and Information Sciences discipline - which is centuries (millennia?) old - has formed around the domain concept. It will help you better dig into the actual business dealings of the domain first before trying to focus too much on the technical/software aspects. The software aspects hinder your initial domain mapping - especially in depth - and business context understanding when you start from a DDD perspective in data.Spend a lot more time on enabling people to understand what data is available. We focus a lot on optimizing for searching "in" data, but we don't spend near...

Interviews with data mesh practitioners, deep dives/how-tos, anti-patterns, panels, chats (not debates) with skeptics, "mesh musings", and so much more. Host Scott Hirleman (founder of the Data Mesh Learning Community) shares his learnings - and those of the broader data community - from over a year of deep diving into data mesh. Each episode contains a BLUF - bottom line, up front - so you can quickly absorb a few key takeaways and also decide if an episode will be useful to you - nothing worse than listening for 20+ minutes before figuring out if a podcast episode is going to be interesting and/or incremental ;) Hoping to provide quality transcripts in the future - if you want to help, please reach out! Data Mesh Radio is also looking for guests to share their experience with data mesh! Even if that experience is 'I am confused, let's chat about' some specific topic. Yes, that could be you! You can check out our guest and feedback FAQ, including how to submit your name to be a guest and how to submit feedback - including anonymously if you want - here: https://docs.google.com/document/d/1dDdb1mEhmcYqx3xYAvPuM1FZMuGiCszyY9x8X250KuQ/edit?usp=sharing Data Mesh Radio is committed to diversity and inclusion.
