+created by the oce package into NetCDF files.
+Objects of the oce have two slots, 'data' and 'metadata',
+that are very significant to the ocencdf package.
+The 'data' contents take the form of vector and array data, and hence can be
+stored in the DATA section of the NetCDF file.  Since these items can be
+accessed easily by standard means of reading NetCDF files, nothing special need
+be explained here.
+However, the 'metadata' contents of oce objects take the form of a tree-like
+structure that cannot be stored in the DATA section of a NetCDF file, which is
+designed for vectors and arrays.  For this reason, the 'metadata' contents are
+stored in a global attribute of the NetCDF file, named &quot;metadata&quot;.  It is in
+JSON format, for ease of parsing in many languages. In R, for example, this can
+be converted using json2metadata(). This
+does more than just translate, however, because JSON format lacks the ability to
+handle some R structures (notably, the 'expression' class).  The following
+explains the changes that are involved in expanding the JSON contents into a
+'metadata' object that mimics that used in the 'oce' package.
+In 'oce', the 'units' structure is broken down into variables (e.g.
+'temperature'), and for each variable there are two quantities stored, one
+called 'units' and the other called 'scale'.  Both are textual in the JSON
+representation, which does not match the 'oce' format, which uses the
+'expression' class for the first of these. In R, the expression may be
+recovered with the 'parse()' function; similar functions exist in
+other analysis languages, if there is a need to e.g. label plot
+axes with subscripts, etc.
+For 'adp' data created from Teledyne-RDI files, the metadata contains a
+matrix named 'codes' that are in 'raw' (byte-level) format.  These are
+converted to integers for the JSON representation, and so if there is a need
+to get the original values, a conversion will be required.

+created by the oce package into NetCDF files.
+Oce objects have two main components, named 'data' and 'metadata'.
+The 'data' contents take the form of vector and array data, and hence can be
+stored in the DATA section of the NetCDF file.  Since these items can be
+accessed easily by standard means of reading NetCDF files, nothing special need
+be explained here.
+However, the 'metadata' contents of oce objects take the form of a tree-like
+structure that cannot be stored in the DATA section of a NetCDF file, which is
+designed for vectors and arrays.  For this reason, the 'metadata' contents are
+stored in a global attribute of the NetCDF file, named &quot;metadata&quot;.  It is in
+JSON format, for ease of parsing in many languages. In R, for example, this can
+be converted using the json2metadata() function of the 'ocencdf' package. This
+does more than just translate, however, because JSON format lacks the ability to
+handle some R structures (notably, the 'expression' class).  The following
+explains the changes that are involved in expanding the JSON contents into a
+'metadata' object that mimics that used in the 'oce' package.
+In 'oce', the 'units' structure is broken down into variables (e.g.
+'temperature'), and for each variable there are two quantities stored, one
+called 'units' and the other called 'scale'.  Both are textual in the JSON
+representation, which does not match the 'oce' format, which uses the
+'expression' class for the first of these. In R, the expression may be
+recovered with the 'parse()' function; similar functions exist in
+other analysis languages, if there is a need to e.g. label plot
+axes with subscripts, etc.
+For 'adp' data created from Teledyne-RDI files, the metadata contains a
+matrix named 'codes' that are in 'raw' (byte-level) format.  These are
+converted to integers for the JSON representation, and so if there is a need
+to get the original values, a conversion will be required.

 # Purpose
 
 The `ocencdf` package provides a way to store approximate forms of oce objects

-useful because Netcdf format is handled in a wide variety of computing languages,
-and is commonly used in data archives.

+It should be noted that the reverse functions are designed to work with NetCDF

 files created by `ctd2ncdf()` based on oce objects.  The reverse functions may
-be able to handle the data portions of other Netcdf files, but they do not parse
-the attribute portions of those Netcdf files in a useful way.  This is because there
-is no way for the code to know what conventions were used in creating an arbitrary
-Netcdf file.  For example, a CTD dataset might record the ship name, the name of
-the research program, etc., but whether these things are recorded in the data section
-of the Netcdf file, or in attributes, or not at all, cannot be known *a priori*,
-and guessing is a risky proposition.
-
-# Limitations of Netcdf format
-
-Unfortunately, direct transferral of R information to Netcdf is not possible.
-This is because Netcdf is an array-oriented format that is not designed to hold
-tree-oriented data such as R lists (which are used throughout oce).  It is
-possible to flatten simple lists, but the process gets complicated for nested
-lists, which are common in oce.  Other difficulties with the Netcdf format
-include its lack of basic elements programming elements such as user-defined
-classes and variable-length character strings in the data portion of the files.
-
-This package is in early development, and efforts are focussed on a single oce
-class, the ctd object.  This focus is intended to permit coding practices to gel,
-in preparation for the addition of other classes.  Given the anticipated needs

 ## Renaming elements
 
 Oce uses a restricted set of names for certain variables.  For example, in ctd
-objects, temperature is called `temperature`, and if the ctd had two temperature
-sensors, there would be an additional entry called `temperature2`.  These are
-not typically the names used in raw data files, however.  More commonly,
-temperature might be named `TEMP`, for example.  In recognition of this, ocencdf
-provides a way to rename oce objects using other systems of names.  The mapping
-between oce name and other name is controlled by YAML (yet another markup
-language) files, which are called varTables in this package. Tables are provided
-for the Argo system and for the World Hydographic Program system. These are
-available as `"argo"` and `"whp"`, respectively.  They are stored in the
-`inst/extdata` directory of the package source tree. Users seeking to define new
-naming systems must copy the formats of those files.
