	Table 1 is a first attempt at a high level summary of selected coupling technologies which serves as a means to quickly compare some of the key features associated with couplers. Dunlap ''et al., ''(2013) describe an approach to assessing coupler features through feature analysis and the creation of feature diagrams, this approach may be considered as a subsequent, more detailed, analysis was required. Carrying out a feature analysis based approach would be much easier to achieve after the couplers described in the following matrix have been whittled down to a short list of candidates.

Carrying out a feature analysis based approach would be much easier to achieve after the couplers described in the following matrix have been whittled down to a short list of candidates.

	The technologies compared in the matrix were specifically identified as being relevant, or potentially relevant, to current BGS activities.		The technologies compared in the matrix were specifically identified as being relevant, or potentially relevant, to current BGS activities.

	<sup>2</sup>Project Trident is a now open source project, originally set up by Microsoft, it is described as ‘a scientific workflow workbench’. The most readily available information on an implementation of the Trident software came from publications and website for the ‘Hydrologists Workbench’, an implementation developed by CSIRO, Australia. The Hydrologists Workbench was used as a proxy for the Trident software when carrying out feature analysis for the matrix, it is therefore possible that some features identified are not fully developed in the original version of the Trident code available via CodePlex.		<sup>2</sup>Project Trident is a now open source project, originally set up by Microsoft, it is described as ‘a scientific workflow workbench’.
