Re: [saf] SAF Issue #14 - Templated syndromes & protocols

[David Snelling <David.Snelling@UK.Fujitsu.com>]

Folks,

First, I would argue against extensions to standard XQuery. However, are we sure there is not a simple way to do this within XQuery? Something like this:

Let

Temp_PARM = 98.6;

in

Signature = /SymptomStore/Symptom[matches(SymptomType,’^health/fever/.*$’) and Content/temperature> Temp_PARM];

Pardon the syntax. The "_PARM" could be suggested as a recommended convention to assist with redeployment, etc.

Folks,

 

The proposal for template syndromes & protocols was to:

1.   Append a /template suffix on to the SyndromeType (and ProtocolType) to indicate it is a template.

2.   Add some kind of token/eyecatcher for substitutable parameters in the Syndrome signature and the Protocol directive.

 

For example, a template syndrome for Fever might look like this:

SyndromeType = health/fever/template

Signature = /SymptomStore/Symptom[matches(SymptomType,’^health/fever/.*$’) and Content/temperature>{temperature}

The {temperature} is the substitutable parameter.

 

One might copy the template, substituting parameters to create a human fever syndrome as follows:

SyndromeType = health/fever/human

Signature = /SymptomStore/Symptom[matches(SymptomType,’^health/fever/.*$’) and Content/temperature>98.6

 

After further discussion today, I’m concerned the proposal for template syndromes/protocols might muddy the spec, as a token in the xquery would mean XQUERY alone isn't sufficient.  Perhaps we add this to our “futures” section, or include in best practices non-normative documents.

 

Thoughts?
