  The Grammar of Institutions, or Institutional Grammar, is an established
approach to encode policy information in terms of institutional statements
based on a set of pre-defined syntactic components. This codebook provides
coding guidelines for a revised version of the Institutional Grammar, the
Institutional Grammar 2.0 (IG 2.0). IG 2.0 is a specification that aims at
facilitating the encoding of policy to meet varying analytical objectives. To
this end, it revises the grammar with respect to comprehensiveness,
flexibility, and specificity by offering multiple levels of expressiveness (IG
Core, IG Extended, IG Logico). In addition to the encoding of regulative
statements, it further introduces the encoding of constitutive institutional
statements, as well as statements that exhibit both constitutive and regulative
characteristics. Introducing those aspects, the codebook initially covers
fundamental concepts of IG 2.0, before providing an overview of pre-coding
steps relevant for document preparation. Detailed coding guidelines are
provided for both regulative and constitutive statements across all levels of
expressiveness, along with the encoding guidelines for statements of mixed form
-- hybrid and polymorphic institutional statements. The document further
provides an overview of taxonomies used in the encoding process and referred to
throughout the codebook. The codebook concludes with a summary and discussion
of relevant considerations to facilitate the coding process. An initial
Reader's Guide helps the reader tailor the content to her interest.
  Note that this codebook specifically focuses on operational aspects of IG 2.0
in the context of policy coding. Links to additional resources such as the
underlying scientific literature (that offers a comprehensive treatment of the
underlying theoretical concepts) are referred to in the DOI and the concluding
section of the codebook.
