The document discusses web-based processing and application patterns for handling Earth Observation (EO) data, detailing the integration of data services and processing environments. It emphasizes reusability, interoperability, and control mechanisms within shared knowledge frameworks, along with use cases for local and remote processes. Through various examples and challenges, it highlights the importance of security, documentation, and data quality in scientific workflows and collaborations.

Editor's Notes
- #28: To wrap things up…
- #29: Re-use existing thinking instead of coming up with something completely new.
- #30: Exchangeability and level of abstraction: Kiemle presentation about choosing the most suitable environment > only if I am that flexible! All kind of interoperability problems: Semantics, Encodings, Interfaces, Access constraints, Information flow is hindered by format problems THE WORLD IS NOT BLACK AND WHITE! Lingua Franca? Will a lowest common denominator work? > With respect to description and programming language Communities have different languages. Security: when using processes internally and externally, I don’t want users and experts to be able to do the same things > need distinctive levels, don’t want others to break my system Reusability: Dynamic allocation and control of ressources, streaming mechanisms Documentation format? Metadata for processes and for process results Discovery > Process Catalog
- #33: Make the world a better place!
