Form Parsing

Must

• Section form using group
• Adding question numbers
• Fix question ordering after parsing

General

• Parallelize algorithms whenever possible
• Parallel parsing of bindings and questions
• Allow additional parser to be added/plugged in
• Accept options to specify missing values and default values per question type
• Parse form description
• Parse form version

Function, Calculation & Formulas

• Implement and evaluate expressions
• Implement and evaluate formulas
• Implement and evaluate functions
• Evaluate calculations
• Implement formula to fill required metadata

Validation & Constraints

• Implement and evaluate constraints
• Validate xForm before parsing

Bindings

• Parse question variable name from nodeset or ref
• Parse, cast and set default values
  • for required set to false
  • for readonly set to false
  • for saveIncomplete set to false
• Parse question relevant and normalize it
• Parse question readonly
• Parse question type, default to string if none present
• parse question type, default to string
• parse preload and property as meta for the form
• convert constraint expressions and regex to javascript compactible

Translation

• parse default language
• normalize default language
• parse translation text
• parse short and long attributes
• parse node with no attributes
• add translation per question
• parse media translation

Instance

• Parse primary instance name or title
• Parse and obtain node default values and set them to default or defaultValue on bindings
• Parse common instance id, version and preloads
• Parse meta and add formula to evaluate them
  • Parse their definition into js object
  • Add default nodejs evealuation logics
• Parse instance structure and obtain it in both xml and json
• Parse metadata as json
• Parse geopoint data

Body

• Parse question index/number
• Parse question page/face
• Parse question nodes attributes
• Parse both nodeset and ref
• Process complex body structure
• Pre-code well known question types
• Parse form input widget to be used in a given question
• Normalize input widgets to be used for html forms
• parse input hint form the input <hint> child node
• Parse geopoint data

Label

• Allow output references to be binded on the label using angular style
  • Need reference fix
• parse default language label from text

Repeat

• findout how repeat questions are submitted in instance
• parse repeated questions and set default repeat count to 1
• parse jr:noAddRemove and default to 'false()'
• prefix variable name with repeat variable

Revelevant

• should parse relevant in the form

{
    reference:'',
    value:'',
    ...
}

• should parse relevant form XPath functions

Widgets

• parse input widget
• parse select1 widget
• parse select widget
• parse upload widget
• parse trigger widget

Controls

• parse group control
• parse repeat control
• parse label control
• parse hint control
• parse output control
• parse item control
• parse itemset control
• parse value control

Meta Questions !!!!! Priority

• should build questions from bindings contains preload and property

Thoughts

• should set default missing value based on data type
• pre code/set default codes to select1 and select items

Urgent

• remove translations from form definition
• Add constraint default messages of non exists
