I've checked in v1.55 as the baseline document content for the face-to-face meeting next week. One renaming: FROM section was section 6 is now section 8. Sections 2-7 define graph patterns Sections 2,3,4,5 are done 6 (Disjunction) and 7 (Unsaid) aren't and need to be be added to complete the graph patterns Section 8 "Choosing what to query" is what was section 6 It's DaveB's text. Moving it out of the pattern section seems to work better and put FROM and SOURCE near each other. Section 9 is SOURCE It currently has two sets of text and needs to be merged Section 10 will be a summary of patterns Section 11 is the query forms: SELECT/CONSTRUCT/DESCRIBE/ASK Sec 11 has the old text from the original description. The SELECT section now includes LIMIT and DISTINCT Section 12 isn't done at all 12.1 will be the subset of standard XQuery/XPath Functions and Operators every implementation must support 12.2 is the extension point for value testing by externally defined boolean-valued functions Andy Contents: * 1 Introduction * 2 Making Simple Queries o 2.1 Writing a Simple Query o 2.2 Triple Patterns o 2.3 Graph Patterns o 2.4 Multiple Matches * 3 Constraining Values * 4 Including Optional Values o 4.1 Optional Bindings o 4.2 Multiple Optional Blocks o 4.4 Defintions * 5 Nested Patterns * 6 More Pattern Matching – Alternatives * 7 More Pattern Matching – Unsaid * 8 Choosing what to query * 9 Querying the Origin of Statements * 10 Summary of Graph Patterns * 11 Query Forms o 11.1 Choosing which Variables to Return o 11.2 Constructing an Output Graph o 11.3 Descriptions of Resources o 11.4 Asking "yes or no" questions * 12 Testing Values o 12.1 Standard operations o 12.2 Extending value testing (I have just noticed the indenting in the TOC is broken for IE - works in Firefox)
