<h2>
<a name="introduction_0">1 Introduction</a>
</h2>
<p>In working on Unicode implementations, it is often useful to access the full content of the Unicode
Character Database (UCD). For example, in establishing mappings from characters to glyphs in fonts, it is
convenient to see the character scalar value, the character name, the character East Asian width, along with
the shape and metrics of the proposed glyph to map to; looking at all this data simultaneously helps in
evaluating the mapping.
</p>
<p>Directly accessing the data files that constitute the UCD is sometimes a daunting proposition. The data is
dispersed in a number of files of various formats, and there are just enough peculiarities (all justified by
the processing power available at the time the UCD representation was designed) to require a fairly intimate
knowledge of the data format itself, in addition to the meaning of the data.
</p>
<p>Many programming environments (for example, Java or ICU) do give access to the UCD. However, those
environments tend to lag behind releases of the standard, or support only some of the UCD content.
</p>
<p>Unibook is a wonderful tool to explore the UCD and in many cases is just the ticket; however, it is
difficult to use when the task at hand has not been built-in, or when non-UCD data is to be displayed as
well.
</p>
<p>This annex presents an alternative representation of the UCD, which is meant to overcome these
difficulties. We have chosen an XML representation, because parsing becomes a non-issue: there are a number
of XML parsers freely available, and using them is often fairly easy. In addition, there are freely
available tools that can perform powerful operations on XML data; for example, XPATH and XQUERY engines can
be thought of as a “grep” for XML data and XSLT engines can be thought of as
“awk” for XML data.
</p>
<p>It is important to note that we are interested in exploring the content of the UCD, rather than in using
the UCD data to process character streams. Thus, we are not concerned so much by the speed of processing or
the size of our representation.
</p>
<p>Our representation supports the creation of documents that represent only parts of the UCD, either by not
representing all the characters, or by not representing all the properties. This can be useful when only
some of the data is needed.
</p>
<p>This annex presents only the XML representation format of the UCD. The data itself is part of the <a href="https://www.unicode.org/reports/tr41/tr41-36.html#UCD">Unicode Character Database</a>.
</p>
<h2>
<a name="overall_schema_0">2 Overall schema</a>
</h2>
<h3>
<a name="general_principles_0">2.1 General principles</a>
</h3>
<p>Our schema can be used to create and validate documents which are intended to represent properties of
Unicode code points, blocks, named sequences, standardized variants, CJK radicals and emoji sources.
A document may represent the values actually assigned in a given version of the UCD, or it may
represent a draft version of the UCD, or a private agreement on Private Use characters. The validity of
a XML document with respect to the schema defined in this annex does not assert anything about the
correctness of the values.
</p>
<p>Valid documents may provide values for only some of the code points, or some of the Unicode
properties. Furthermore, they may also incorporate non-Unicode properties.
</p>
<p>Our schema is defined using English. However, a useful subset of the validity constraints can be
captured using a schema language, thereby simplifying the task of validating documents. We have chosen
Relax NG [<a href="https://www.unicode.org/reports/tr41/tr41-36.html#ISO19757">ISO 19757</a>],
in the compact syntax , as the schema language. It is important to stress that the schema which is
defined in English imposes more constraints on the documents than can be validated with the Relax NG
schema.
</p>
<p>An important characteristic of Relax NG is that its schemas do not modify or augment the infoset of
the documents. Therefore, it is possible to process our XML representation without using the schema.
Also, the schema is relatively straightforward and can be converted mechanically to other schema
languages.
</p>
<p>While our XML representation is not intended to be used during processing of characters and strings,
it is still a design principle for our schema to support the relatively efficient representation of the
UCD. This is achieved by an inheritance mechanism, similar to property inheritance in CSS or in XSL:FO
(see section 4.3 Group).
</p>
<p>Many invariants impose constraints on the values of the different properties for a given code point.
For example, if the value of the Numeric Type property is None, then the value of the
Numeric Value property should be the empty string; and if the value of the Other
Alphabetic property is true, then the value of the Alphabetic property should be
true. Those invariants are not captured in the schema.
</p>
<h3>
<a name="namespace_0">2.2 Namespace</a>
</h3>
<p>The namespace for our elements is “http://www.unicode.org/ns/2003/ucd/1.0”. Our
attributes are in the empty namespace.
</p>
<p>
<i>
<a name="ucdxml:namespace_declaration_1">[namespace declaration,
1]
</a>
=</i>
<tt style="white-space: pre;">
default namespace ucd = "http://www.unicode.org/ns/2003/ucd/1.0"
</tt>
</p>
<p>In all our examples, we assume that this namespace is the default one.
</p>
<h3>
<a name="datatypes_0">2.3 Datatypes</a>
</h3>
<p>We use a standard XML Schema datatypes:</p>
<p>
<i>
<a name="ucdxml:datatypes_declaration_2">[datatypes declaration,
2]
</a>
=</i>
<tt style="white-space: pre;">
# default; datatypes xsd = "http://www.w3.org/2001/XMLSchema-datatypes"
</tt>
</p>
<p>Characters are pervasive in the UCD, and will need to be represented. Representing characters directly
by themselves would seem the most obvious choice; for example, we could express that the decomposition
of U+00E8 is “&#x0065;&#x0300;”, that is have exactly two characters in (the
infoset of) the XML document. However, the current XML specification limits the set of characters
that can be part of a document. Another problem is that the various tools (XML parser, XPATH engine,
etc.) may equate U+00E8 with U+0065 U+0300, thus making it difficult to figure out which of the two
sequences is contained in the database (which is sometimes important for our purposes). Therefore, we
chose instead to represent characters by their code points; we follow the usual convention of four to
six hexadecimal digits (uppercase) and code points in a sequence separated by space; for example, the
decomposition of U+00E8 will be represented by the nine characters “0065 0300” in the
infoset.

<h3>

<p>A large number of properties are boolean. We uniformly use the values <tt>Y</tt> and
<tt>N</tt> for those:
</p>
<p>
<i>
<a name="ucdxml:boolean_5">[boolean,

</a>
=</i>
<tt style="white-space: pre;">
boolean = "Y" | "N"
</tt>
</p>
<h3>
<a name="ordering_of_elements_0">2.6 Ordering of elements</a>
</h3>
<p>In elements that hold lists of child elements, such as <tt>repertoire</tt>,
<tt>group</tt>, or <tt>standardized-variants</tt>, the schema does not require that the
child elements be in any particular order.
</p>
<h2>
<a name="description_0">3 Description</a>
</h2>
<p>The root element may have a <tt>description</tt> child element, which in turn contains any string,
which is meant to describe what the XML document purports to describe.
</p>
<p>It is recommended that if the document purports to represent the UCD of some Unicode version, the
<tt>description</tt> be selected in accord with the rules listed in <a href="https://www.unicode.org/reports/tr41/tr41-36.html#Versions">[Versions]</a>; and
conversely, that documents which do not purport to represent the UCD be described as such.
</p>
<p>
<i>
<a name="ucdxml:description_6">[description,
6]
</a>
=</i>
<tt style="white-space: pre;">
ucd.content &=
element description { text }?
</tt>
</p>
<h2>
<a name="repertoire_0">4 Repertoire</a>
</h2>
<p>The <tt>repertoire</tt> child element of the <tt>ucd</tt> element describes the code points and
their properties. As we will see shortly, code points can be described individually or as part of a group:
</p>
<p>
<i>
<a name="ucdxml:repertoire_7">[repertoire,
7]
</a>
=</i>
<tt style="white-space: pre;">
ucd.content &=
element repertoire { (code-point | group) + }?
</tt>
</p>
<h3>
<a name="sets_of_code_points_0">4.1 Sets of code points</a>
</h3>
<p>It is often the case that successive code points have the same property values, for a given set of
properties. The most striking example is that of an unallocated plane, where all but the last two
code points are reserved and have the same property values. Another example is the URO (U+4E00
.. U+9FA5) where all the code points have the same property values if we ignore their name and their
Unihan properties.
</p>
<p>
<i>
<a name="ucdxml:set_of_code_points_8">[Set of code points,
8]
</a>
=</i>
<tt style="white-space: pre;">
set-of-code-points =
attribute cp { single-code-point }
| ( attribute first-cp { single-code-point },
attribute last-cp { single-code-point } )
</tt>
</p>
<p>This observation suggests that it is profitable to represent sets of code points which share the
same properties, rather than individual code points. To make the representation of the sets simple,
we restrict them to be segments in the code point space, that is a set is defined by the first and
last code point it contains. Those are captured by the attributes <tt>first-cp</tt> and <tt>
last-cp</tt>. The attribute <tt>cp</tt> is a shorthand notation for the case where the set
has a single code point.
</p>
<p>In the <tt>repertoire</tt>, there must be at most one <tt>code-point</tt>
element for a given code point.
</p>
<h3>
<a name="code_point_types_0">4.2 Code point types</a>
</h3>
<p>When thinking about Unicode code points, it is useful to split them into four types:
</p>
those assigned to abstract characters (PUA or not)
the noncharacters
the surrogate code points
the reserved code points
<p>This leads to four elements to describe sets of code points:
</p>
<p>
<i>
<a name="ucdxml:code_points_9">[Code points,
9]
</a>
=</i>
<tt style="white-space: pre;">
code-point |=
element reserved {
set-of-code-points,
code-point-attributes }
code-point |=
element noncharacter {
set-of-code-points,
code-point-attributes }
code-point |=
element surrogate {
set-of-code-points,
code-point-attributes }
code-point |=
element char {
set-of-code-points,
code-point-attributes }
</tt>
</p>
<h3>
<a name="group_0">4.3 Group</a>
</h3>
<p>While we already recognized the situation where a set of code points have exactly the same set of
property values, another common situation is that of code points which have almost all the same
property values.
</p>
<p>For example, the characters U+1740 BUHID LETTER A .. U+1753 BUHID VOWEL SIGN U all have the age
“3.2”, and all have the script “Buhd”. On the one hand, it is convenient
to support data files in which those properties are explicitly listed with every code point, at this
makes answering questions like “what is the age of U+1749?” easier, because that data
is expressed right there. On the other hand, this leads to rather large data files, and it also tends
to obscure the differences between similar characters.
</p>
<p>Our representation accounts for this situation with the notion of groups. A
<tt>group</tt> element is simply a container of code points that also holds default values for
the properties. If a code point inside a <tt>group</tt> does not list explicitly a property but the
<tt>group</tt> lists it, then the code point inherits that property from its
<tt>group</tt>. For example, the fragment with explicit properties:
</p>
<pre>
<char cp="1740" age="3.2" na="BUHID LETTER A" gc="Lo" sc="Buhd"/>
<char cp="1741" age="3.2" na="BUHID LETTER I" gc="Lo" sc="Buhd"/>
<char cp="1752" age="3.2" na="BUHID VOWEL SIGN I" gc="Mn" sc="Buhd"/>
<char cp="1820" age="3.0" na="MONGOLIAN LETTER A" gc="Lo" sc="Mong"/></pre>
<p>is equivalent to this fragment which uses a <tt>group</tt>:
</p>
<pre>
<group age="3.2" gc="Lo" sc="Buhd">
<char cp="1740" na="BUHID LETTER A"/>
<char cp="1741" na="BUHID LETTER I"/>
<char cp="1752" na="BUHID VOWEL SIGN I" gc="Mn"/>
<char cp="1820" age="3.0" na="MONGOLIAN LETTER A" sc="Mong"/>
</group></pre>
<p>The element for U+1740 does not have the <tt>age</tt> attribute, and it therefore inherits it
from its enclosing <tt>group</tt> element, that is “3.2”. On the other hand,
the element for U+1820 does have this attribute, so the value is “3.0”.
</p>
<p>As this example illustrates, the notion of <tt>group</tt> does not necessarily align with the
notion of Unicode block. It is entirely defined and limited to our representation. In particular, the
value of a property for a code point can always be determined from the XML document alone, assuming
that this property and this code point are expressed at all. Of course, one may create an XML
representation where the groups happen to coincide with the Unicode blocks.
</p>
<p>Groups cannot be nested. The motivation for this limitation is to make the life of consumers
easier: either a property is defined by the element for a code point, or it is defined by the
immediately enclosing <tt>group</tt> element.
</p>
<p>For UCDXML versions prior to 17.0, only non-Unihan attributes are applied to the <tt>group</tt>
elements. Starting with 17.0, Unihan attributes are also applied to the <tt>group</tt> elements.
</p>
<p>
<i>
<a name="ucdxml:groups_10">[groups,
10]
</a>
=</i>
<tt style="white-space: pre;">
group =
element group {
code-point-attributes,
code-point* }
</tt>
</p>
<h3>
<a name="properties_0">4.4 Properties</a>
</h3>
<p>Each property, except for the Special_Case_Condition and Name_Alias
properties, is represented by an attribute. In an XML data file, the absence of an attribute (may be
only on some <code>code-point</code>s) means that the document does not express the value
of the corresponding property. Conversely, the presence of an attribute is an expression of the
corresponding property value; the implied null value is represented by the empty string.
</p>
<p>The Name_Alias property is represented by zero or more <tt>name-alias</tt> child
elements. Unlike the situation for properties represented by attributes, it is not possible to determine
whether all the aliases have been represented in a data file by inspecting that data file.
</p>
<p>The name of an attribute is the abbreviated name of the property as given in the file
PropertyAliases.txt in the corresponding version of the UCD. For the Unihan
properties, the name is that given in the various versions of the Unihan database.
</p>
<p>For catalog and enumerated properties, the values are those listed in the file
PropertyValueAliases.txt in the corresponding version of the UCD; if there is an abbreviated
name, it is used, otherwise the long name is used.
</p>
<p>Note that the set of possible values for a property captured in this schema may change from one
version to the next.
</p>
<h4>
<a name="age_property_0">4.4.1 Age property</a>

<p>The majority of the characters in Unicode have a name which is of the form CJK UNIFIED
IDEOGRAPH-<code><code point></code>. It also happens that character names cannot
contain the character U+0023 # NUMBER SIGN, so we adopted the following convention: if a
code point has the attribute <tt>na</tt> (either directly or by inheritance from an enclosing
group), then occurrences of the character # in the name are to be interpreted as the value of the
code point. For example:
</p>
<pre>
<char cp="3400" na="CJK UNIFIED IDEOGRAPH-3400"/></pre>
<p>and</p>
<pre>
<char cp="3400" na="CJK UNIFIED IDEOGRAPH-#"/></pre>
<p>are equivalent. The # can be in any position in the value of the <tt>na</tt>
attribute. The convention also applies just as well to a set of multiple code points:
</p>
<pre>
<char cp="3400" na="CJK UNIFIED IDEOGRAPH-3400"/>
<char cp="3401" na="CJK UNIFIED IDEOGRAPH-3401"/></pre>
<p>is equivalent to</p>
<pre>
<char cp="3400" na="CJK UNIFIED IDEOGRAPH-#"/>
<char cp="3401" na="CJK UNIFIED IDEOGRAPH-#"/></pre>
<p>which in turn is equivalent to:</p>
<pre>
<char first-cp="3400" last-cp="3401" na="CJK UNIFIED IDEOGRAPH-#"/></pre>

<p>Most characters have a case mapping and case folding properties that simply map or fold to
themselves. This is very similar to the situation we encountered with names, and we adopted a
similar convention: if the value of a case mapping or case folding property is the character
itself, we use the attribute value # (U+0023 # NUMBER SIGN) as a shorthand notation; this
enables those attributes to be captured in groups.

<p>The simple case mappings are recorded in the <tt>suc</tt>, <tt>slc</tt>, <tt>stc</tt>
