Atoms

Atoms can be used to add information from a set of selected records into the report text. To incorporate Atoms into a report the ato namespace is defined in the Report.

<rep:Report 
  xmlns:rep="http://safe.epcc.ed.ac.uk/report"
  xmlns:par="http://safe.epcc.ed.ac.uk/parameter"
  xmlns:per="http://safe.epcc.ed.ac.uk/period"
  xmlns:fil="http://safe.epcc.ed.ac.uk/filter"
  xmlns:ato="http://safe.epcc.ed.ac.uk/atom">

Count

The number of selected record can be output using the Count tag.

The user ran <ato:Count/> jobs.

Sum

The sum of a numeric property of the selected records can be output using the Sum tag.

The user ran used <ato:Sum>Wall</ato:Sum> seconds.

Average

The average of a numeric property of the selected records can be output using the Average tag. If both upper and lower time bounds have been specified in the filter this will be a time average of the quantity. Otherwise it will be a simple average over the matching records.

The user ran an average of <ato:Average>Wall</ato:Average> seconds. 

Minimum

The minimum value of a numeric or date property of the selected records can be output using the Minimum tag.

The user used a minimum of <ato:Minimum>Wall</ato:Minimum> seconds. 

Maximum

The maximum value of a numeric or date property of the selected records can be output using the Maximum tag.

The user used a maximum of <ato:Maximum>Wall</ato:Maximum> seconds. 

Atom

The Atom element can be used to add filter elements.

Your project used a maximum of 
<ato:Atom>
<fil:Filter>  
        <fil:EQ>
                <fil:Property>Project</fil:Property>
                <fil:Value>myproject</fil:Value>
        </fil:EQ>               
</fil:Filter>
<ato:Maximum>Wall</ato:Maximum> 
</ato:Atom>
seconds. 

Each bottom level atom element generates a single value using a separate query to the underlying data. These can be combined using the Add, Sub,Mul and Div elements. Constant values can be introduced into these expressions using the Number element.
