# - CLDR (the source of most of the data, and some Java tools)
# - ICU4J (used only for checking the converted data)
# - ICU4C (the destination for the new data, and the source for some of it)
-# (Either check out ICU4C from Subversion, or download the additional
-# icu4c-*-data.zip file so that the icu/source/data/ directory is fully
-# populated.)
#
# For an official CLDR data integration into ICU, these should be clean, freshly
# checked-out. For released CLDR sources, an alternative to checking out sources
# ICU is the version number and/or a CLDR svn tag name for the revision of CLDR
# that was the source of the data for that release of ICU.
#
-# Note: Some versions of the OpenJDK will not build the CLDR java utilities.
-# If you see compilation errors complaining about type incompatibilities with
-# functions on generic classes, try switching to the Sun JDK.
-#
# Besides a standard JDK, the process also requires ant
# (http://ant.apache.org/),
# plus the xml-apis.jar from the Apache xalan package

#
+# CLDR dtd caching
+#
+# Parts of the build process (notably building the new ICU data files in step 4)
+# require http: access to files in the CLDR repository; for example, processing
+# the files in icu4c/source/data/xml/ may require access to
+# http://www.unicode.org/repos/cldr/trunk/common/dtd/ldml.dtd
+#
+# Unless you cache the dtds locally by
+# 1. creating a temp directory e.g. ~/.cldrdtd
+# 2. setting CLDR_DTD_CACHE to it e.g. -DCLDR_DTD_CACHE=~/.cldrdtd
+# your system will make excessive network requests, which will result in the
+# Unicode server blocking access.
+#
+#----
+#
# There are several environment variables that need to be defined.
#
# a) Java- and ant-related variables
#
# ANT_OPTS: You may want to set:
#
-# -Xmx3072m, to give Java more memory; otherwise it may run out
+# -Xmx4096m, to give Java more memory; otherwise it may run out
# of heap.
+# -DCLDR_DTD_CACHE=~/.cldrdtd (or some other temp directory
+# that already exists), to reduce frequent http: access to dtds
+# and consequent blockage by Unicode server.
#
# b) CLDR-related variables
#
# CLDR_DIR: Path to root of CLDR sources, below which are the common and
# tools directories.
-# CLDR_CLASSES: Defined relative to CLDR_DIR. It only needs to be set if you
-# are not running ant jar for CLDR and have a non-default output
-# folder for cldr-tools classes.
+# CLDR_CLASSES: Path to the CLDR Tools classes directory. If not set, defaults
+# to $CLDR_DIR/tools/java/classes
#
# c) ICU-related variables
# These variables only need to be set if you're directly reusing the
# files are used in addition to the CLDR files as inputs to the CLDR data build
# process for ICU):
#
-# icu/trunk/source/data/icu-config.xml - Update <locales> to add or remove
+# icu4c/source/data/icu-config.xml - Update <locales> to add or remove
# CLDR locales for inclusion in ICU. Update <paths> to prefer
# alt forms for certain paths, or to exclude certain paths; note
# that <paths> items can only have draft or alt attributes.
# should also be included in <locales>, per PMC policy decision
# 2012-05-02 (see http://bugs.icu-project.org/trac/ticket/9298).
#
-# icu/trunk/source/data/build.xml - If you are adding or removing break
+# icu4c/source/data/build.xml - If you are adding or removing break
# iterators, you need to update <fileset id="brkitr" ...> under
# <target name="clean" ...> to clean the correct set of files.
#
-# icu/trunk/source/data/xml/ - If you are adding a new locale, break
+# If there are new CLDR resource bundle types, you may need to
+# updated the <remapper> sections to put these in the correct
+# data subfolder for ICU.
+#
+# icu4c/source/data/xml/ - If you are adding a new locale, break
# iterator, collation tailoring, or rule-based number formatter,
# you may need to add a corresponding xml file in (respectively)
# the main/, brkitr/, collation/, or rbnf/ subdirectory here.
# common/dtd/ldml.dtd - update cldrVersion
# common/dtd/ldmlBCP47.dtd - update cldrVersion
# common/dtd/ldmlSupplemental.dtd - update cldrVersion
+# common/dtd/ldmlSupplemental.dtd - updateunicodeVersion
+# keyboards/dtd/ldmlKeyboard.dtd - update cldrVersion
# tools/java/org/unicode/cldr/util/CLDRFile.java - update GEN_VERSION

+# Unfortunately, even if you have your DTD cache variable enabled, you may still
