Dakota Keywords
===============

Valid Dakota input keywords are dictated by dakota.xml, included in source and binary distributions of Dakota. This specification file is used with the NIDR[29] parser to validate user input and is therefore the definitive source for input syntax, capability options, and optional and required capability sub-parameters for any given Dakota version. A more readable variant of the specification dakota.input.summary is also distributed.

While complete, users may find dakota.input.summary overwhelming or confusing and will likely derive more benefit from adapting example input files to a particular problem. Some examples can be found here: Sample Input Files. Advanced users can master the many input specification possibilities by understanding the structure of the input specification file.

===================
Input Spec Overview
===================

Refer to the dakota.input.summary file, in Input Spec Summary, for all current valid input keywords.

- The summary describes every keyword including:

  - Whether it is required or optional
  - Whether it takes ARGUMENTS (always required) Additional notes about ARGUMENTS can be found here: Specifying Arguments.
  - Whether it has an ALIAS, or synonym
  - Which additional keywords can be specified to change its behavior
  
- Additional details and descriptions are described in Keywords Area
- For additional details on NIDR specification logic and rules, refer to[29] (Gay, 2008).

==================
Input Spec Summary
==================

This file is derived automatically from dakota.xml, which is used in the generation of parser system files that are compiled into the Dakota executable. Therefore, these files are the definitive source for input syntax, capability options, and associated data inputs. Refer to the Developers Manual information on how to modify the input specification and propagate the changes through the parsing system.

Key features of the input specification and the associated user input files include:

- In the input specification, required individual specifications simply appear, optional individual and group specifications are enclosed in [], required group specifications are enclosed in (), and either-or relationships are denoted by the | symbol. These symbols only appear in dakota.input.summary; they must not appear in actual user input files.
- Keyword specifications (i.e., environment, method, model, variables, interface, and responses) begin with the keyword possibly preceded by white space (blanks, tabs, and newlines) both in the input specifications and in user input files. For readability, keyword specifications may be spread across several lines. Earlier versions of Dakota (prior to 4.1) required a backslash character (\) at the ends of intermediate lines of a keyword. While such backslashes are still accepted, they are no longer required.
- Some of the keyword components within the input specification indicate that the user must supply INTEGER, REAL, STRING, INTEGERLIST, REALLIST, or STRINGLIST data as part of the specification. In a user input file, the "=" is optional, data in a LIST can be separated by commas or whitespace, and the STRING data are enclosed in single or double quotes (e.g., 'text_book' or "text_book").
- In user input files, input is largely order-independent (except for entries in lists of data), case insensitive, and white-space insensitive. Although the order of input shown in the Sample Input Files generally follows the order of options in the input specification, this is not required.
- In user input files, specifications may be abbreviated so long as the abbreviation is unique. For example, the npsol_sqp specification within the method keyword could be abbreviated as npsol, but dot_sqp should not be abbreviated as dot since this would be ambiguous with other DOT method specifications.
- In both the input specification and user input files, comments are preceded by #.
- ALIAS refers to synonymous keywords, which often exist for backwards compatability. Users are encouraged to use the most current keyword.
