<title>Itzulpen datu-basea</title>

<para>Itzulpen datu-baseak Berkeley Database IIan oinarritutako datu-base batean itzulpenak biltegiratzeko aukera ematen dizu &ie; zure diskoko fitxategi bitar batean biltegiratzen da. Datu-baseak bilaketa azkarra bermatzen du itzulpen-kopuru handi batean.</para>

<para>Modu hau &kbabel;-ekin ondoen integratzen denetako bat da. Bilaketaz eta itzulpen-zirriborroaz gain, ondoko gailuak onartzen ditu:</para>

<itemizedlist> <listitem> <para>&kbabel;-en editorean idatzitako itzulpen berri guztiak automatikoki biltegiratu daitezke datu-basean.</para> </listitem> <listitem> <para>Datu-base hau <acronym>msgid</acronym> <quote>parekatzeko (Diff)</quote> erabil daiteke.</para> </listitem> </itemizedlist>

<para>Jakina, datu-basean zenbat eta itzulpen gehiago biltegiratu, orduan eta produktiboa izan zaitezke. Datu-basea betetzeko, <guilabel>Datu-basea</guilabel> tabulatzailea erabil dezakezu hobespenen elkarrizketan edo itzulitako mezu guztien gehikuntza automatikoa tabulatzaile berean piztu dezakezu.</para>

<para>
The <guilabel>Search</guilabel> tab contains finer specification for searching the text.
You can define how to search and also allows to use another special way of searching
called <emphasis><guilabel>Word substitution</guilabel></emphasis>. By substituting
one or two words the approximate text can be found as well. For example, assume you
are trying to find the text <userinput>My name is Andrea</userinput>.
</para>

  <varlistentry>
    <term><guilabel>Equal</guilabel></term>
    <listitem>
    <para>
    Text from database matches if it is the same as the searched string. In our example it can
    be <emphasis>My name is !amp-internal!Andrea</emphasis> (if !amp-internal! is set as ignored character
    in <guilabel>Characters to be ignored</guilabel> on <guilabel>Generic</guilabel> tab).

    be <emphasis>My name is Andrea, you know?</emphasis>.
    </para>
    </listitem>
  </varlistentry>
  <varlistentry>
    <term><guilabel>Query contains</guilabel></term>
    <listitem>
    <para>
    Text from database matches if the searched string contains it. For our example it can
    be <emphasis>Andrea</emphasis>. You can use this for enumerating the possibilities to
    be found.

  </varlistentry>
<varlistentry>
    <term><guibutton>Use one word substitution</guibutton></term>
    <listitem>
    <para>
    If the query text contains less words than specified below, it also
    tries to replace one of the words in the query. In our example it will
    find <emphasis>Your name is Andrea</emphasis> as well.
    </para>

<varlistentry>
    <term><guibutton>Max number of words in the query</guibutton></term>

<sect2 id="database-fill">
<title>Filling the database</title>
<para>
The <guilabel>Database</guilabel> tab allows to define where is the database stored on
disk (<guilabel>Database directory</guilabel>) and if it should be used for automatic
storing of the new translations (<guibutton>Auto add entry to database</guibutton>).
In this case you should specify the author of the new translation in <guilabel>Auto added
entry author</guilabel>.
</para>
<para>
The rest of the tab allows you to fill the database from already existent PO files. Use one
of the buttons in the middle of the dialog box. The progress of the file loading will be
shown by progress bars below the buttons. The <guilabel>Repeated strings</guilabel>
button should be used in special case when one translated string is repeated many
times, so you do not want to store too many of them. Here you can limit the stored strings.

<title>Defining good keys</title>
<para>
On the <guilabel>Good keys</guilabel> tab are the thresholds to specify how to fill 
the list of good keys.
<guilabel>Minimum number of query words in the key (%)</guilabel> specifies exactly that.
Text will need to contain only this per cent of the words to qualify as good key. Opposite can
be specified via <guilabel>Minimum number of words of the key also in the query (%)</guilabel>.
The length of the words can be set by <guilabel>Max length</guilabel> spinbox.
</para>
<para>Searched text typically contains number of generic words, &eg; articles. You can
eliminate the words based on the frequency. You can discard them by 
<guilabel>Discard words more frequent than</guilabel> or consider as always present by
<guilabel>frequent words are considered as in every key</guilabel>. This way the
frequent words will be almost invisible for queries.

<sect1 id="auxiliary">
<title>Auxiliary PO file</title>

<para>This searching mode is based on matching the same original
English string (the msgid) translated in some other language in an
auxillary <acronym>PO</acronym> file.  It is very common for romanic
languages to have similar words, similarly for for anglosaxon and
slavonic ones.</para>

<para>For example, say I wanted to translate the word
<quote>on</quote>, from <filename>tdelibs.po</filename>, into Romanian
but have no clue.  I look in the same file for French and find
<quote>actif</quote>, and in the Spanish one find
<quote>activado</quote>.  So, I conclude that the best one in Romanian
will be <quote>activ</quote>.  &kbabel; automates this task.
Currently you can define only one auxiliary file to search.</para>

  <guimenuitem>PO Auxiliary</guimenuitem>
</menuchoice>
from the &kbabel; menu.</para>

<para>In the <guilabel>Configure Dictionary PO Auxiliary</guilabel>
dialog you can select the path to the auxiliary <acronym>PO</acronym>
file.  To automate <acronym>PO</acronym>-file switching when you
change current edited file there are many variables delimited by
<literal>@</literal> char that are replaced by appropriate
values:</para>

<variablelist>
  <varlistentry>
    <term>@PACKAGE@</term>
    <listitem><para>
      The name of application or package currently being translated.
      For example, it can expand to kbabel, tdelibs, konqueror

<para>In the edit line the actual path to the auxiliary

provided variables in a path it is possible to choose an absolute,
real path to an existing <acronym>PO</acronym> file.  Let's take an
example.</para>

<para>I'm Romanian and I have some knowledge about French language and
I work on &kde; translation.</para>

<para>First step is to download a very fresh
<filename>tde-i18n-fr.tar.bz2</filename> from the <ulink
url="ftp://ftp.kde.org/pub/kde/snapshots/current/tde-i18n">&kde; &FTP;

hard-disk a French translation tree. I do this into
<filename>/home/clau/cvs-cvs.kde.org/tde-i18n/fr</filename>.</para>

<para>My <acronym>PO</acronym> sources directory is in
<filename>/home/clau/cvs-cvs.kde.org/tde-i18n/ro</filename>.  Don't
forget to select <guilabel>PO Auxiliary</guilabel> as the default

<title>PO compendium</title>

<para>A compendium is a file containing a collection of all
translation messages (pairs of <acronym>msgid</acronym> and
<acronym>msgstr</acronym>) in a project, &eg; in &kde;. Typically,
compendium for a given language is created by concatenating all
<acronym>PO</acronym> files of the project for the
language. Compendium can contain translated, untranslated and fuzzy
messages. Untranslated ones are ignored by this module.  </para>

<para>Similarly to Auxiliary <acronym>PO</acronym>, this searching
mode is based on matching the <quote>same</quote> original string
(<acronym>msgid</acronym>) in a compendium. Currently you can define
only one compendium file to search.  </para>

<para>This mode is very useful if you are not using the translation
database and you want to achieve consistent translation with other
translations. By the way, compendium files are much easier to share
with other translators and even other translation projects because
they can be generated for them as well.  </para>

options, where you can specify how the text is compared and whether to
ignore fuzzy translations, and message-matching options, which

searching message or vice versa.</para>
