The framework of building a distributed ocean observing software system based on complex virtual instruments (CVIs), which are used for processing and displaying the collected data from ocean instruments and the related metadata, is defi ned in this standard. This framework provides the guidelines for the CVI-based development process, in which CVI structure design covers management of observed data and metadata, virtual instrument engine based on geospatial information, and service interfaces for CVI interactions.

This standard defines the framework of building distributed ocean observing software systems based on complex virtual instruments (CVIs), which are used for processing and displaying the collected data from ocean instruments and the related metadata (Guo, et al. [B1]). This framework provides the guidelines for a CVI based development process, in which CVI structure design covers management of observed data and metadata, virtual instrument engine based on geospatial information, and service interfaces for CVI interactions. CVI mapping schemes describe the correspondence from observed objects to CVIs. CVI relations define the relationships between CVIs, and d...

The purpose of this standard is to advise and assist developers in adopting a CVI-based development method in building ocean observing software systems. Implementation of this standard simplifies the software development process greatly, which is turned into compositing CVIs that are customized according to specific requirements by means of CVI interfaces. Implementation of this standard also forms a set of reusable CVIs that can be shared among ocean communities. The development efficiency is improved because customization tools are provided to avoid code programming.
