In environments where infrastructure is developed over decades by many different actors using solutions from different vendors and manufacturers, systems often become fragmented. Operators are then forced to work with multiple incompatible tools, technologies, data formats, and workflows, making planning, construction, daily operation, maintenance, expansion, integration, and staff training increasingly complex and costly.

	This fragmentation ~~often results in vendor lock-in, where systems depend~~ on specific ~~tools~~, ~~expertise~~, or ~~suppliers~~ that may ~~not remain~~ available over the full lifecycle of the infrastructure.		This fragmentation can also create dependencies on specific products, suppliers, software, or specialist expertise that may no longer be available over the full lifecycle of the infrastructure.

	An open standard ~~provides a~~ shared ~~technical foundation that enables interoperability and ensures systems can be maintained~~ and ~~extended independently of any single product or provider~~.		AOWIS addresses this by providing a shared open system for planning, designing, building, operating, maintaining, extending, and managing water and agricultural infrastructure. It combines a common technical standard with open-source software, engineering guidance, shared knowledge, reference implementations, and operational practices.

	AOWIS ~~defines such a foundation for water~~ and ~~agricultural~~ infrastructure ~~under~~ real-world operational ~~constraints~~.		The '''AOWIS Standard''' forms the normative technical core of this system, providing common requirements and interfaces that support interoperability and help infrastructure remain understandable, maintainable, and extensible independently of any single vendor or product.
