3.1: High level requirement categories
The following sections will briefly discuss more details on the various cate- gories to ensure a robust baseline for the development of an SDI for the Arctic
architecture and governance as discussed in chapters 4
and 5
.
3.1 Open Data Data Sharing
Open Data Data sharing addresses both legal as well as technical aspects such as how to enable data sharing among disparate and heterogeneous endpoints
and systems using common data models and schemas. Open data is the idea that some data should be freely available to everyone to use and republish as
they wish, without restrictions from copyright, patents or other mechanisms of control. Open Data Data Sharing further addresses organizational aspects
such as how to encourage data sharing with social or economic incentives and enforcement of rules.
• Any SDI with Arctic data shall broker the delivery of government and non-governmental Arctic observations
• Integration of near real-time observations from both satellites and in-situ sensors is key. Traditionally, this has not been easily achieved due to the

26 proprietary nature of the sensor interfaces. New technologies such as Sen-
sorThings API shall be implemented. Also, auto-registry of sensors is a key requirement.
• The architecture shall support creation and exchange of research-oriented synthesized data sets i.e. simulation model outputs
• All data shall be accompanied by metadata. As this requirement is ex- tremely tough to implement, new ways shall be explored to minimize the
need for manually generated metadata.
3.2 Standards and Interoperability
Standards and Interoperability addresses mechanisms and agreements to ensure that components being part of or that are loosely connected to an SDI for the
Arctic can communicate with each other.
• Interoperability of SDI components across platforms is of overall impor- tance
• Data shall be served at standardized Web interfaces using standardized encodings.
• Standards-based Web GIS integrates and leverages all the investments that have already been made in GIS standards, data, and technologies.
Any SDI for the Arctic should benefit from these investments and should be based on Web GIS patterns.
• Detailed compliance tests shall be available to ensure interoperability across components
