•	Figures have been converted into patterns to remove colours. It may be better to use grayscales rather than patterns.
 Ellen to tweak the figures a bit more.
•	Figure 1: qualify info and data model ovals with ‘OGF’.
•	Figure 3: Add the GLUE name in. Clarify the information & data model boxes so they match Figure 1 by moving some of 
the diagram into text before the figure.  Alternative (probably better given complexity of diagram) suggested by David 
Snelling is to remove the ref and info model layers and elaborate in text the derivations (avoids adding more arrows) –
 so Figure 3 is now a drill down of figures 1 and 2.  David’s proposal was accepted.
•	Section 4: Changed the example to match other published examples. OK.
