      <p><h3><a name="intro">Introducci</a></h3>
      <p>Els enllaos a altres idiomes, tamb coneguts com a 'altlangs', sn dispositius interns que es fan servir per mostrar la relaci entre dues categories en idiomes diferents.</p>
      <p>Potser t'hauras adonat que DMOZ t una categoria de primer nivell anomenada <a href="http://dmoz.org/World/">World/</a> on hi ha enllaos a llocs web que no estan en angls. Les categories World/<idioma> estan organitzades d'una manera similar al costat angls del directori. Sobretot pel que fa a les categories de primer nivell. Un dels motius d'aquesta similitud s que facilita l'enlla entre categories de temtica idntica.</p>
      <h3><a name="block">El bloc de text d'altlang</a></h3>
      <p>Generalment, tots els altlangs d'una categoria es troben al bloc de text d'altlang. Aix es deu a que tant el que es veu a l'editar una categoria com la interficie pblica de la categoria, els altlangs estan aliniats en un bloc de text a la part dreta de la pgina.</p>
      <p>A la part pblica el bloc de text est situat sota el text: "Aquesta categoria en altres idiomes".</p>
      <p>En el bloc de text d'altlang els ttols que enllaen estan escrits en l'idioma de la categoria on es troben. Per exemple, <a href="http://dmoz.org/Recreation/">Recreation/</a> enllaa al seu equivalent en <a href="http://dmoz.org/World/Espa%f1ol/Recreaci%f3n/">Castell</a> amb la paraula 'Spanish', per l'equivalent en castell de Recreation/ s <a href="http://dmoz.org/World/Espa%f1ol/Recreaci%f3n/">World/Espaol/Recreacin</a>, i t un enlla recproc que es diu 'Ingls' (la en castell per dir 'English').</p>
      <h3><a name="uses">Utilitat dels altlangs</a></h3>
      <p>Els usuaris que parlen ms d'un idioma normalment fa servir els altlangs per a poder accedir, per exemple, a llocs web escrits en angls sobre salut, i llocs web escrits en rus sobre salut. Si es fan servir apropiadament, els altlangs permeten a aquests usuaris canviar entre idiomes indistintament.</p>
      <p>Els editors poden fer servir els altlangs per enviar els llocs web proposats incorrectes a la categoria correcte en altres idiomes. Per facilitar aquest procs, a les categories que disposen d'aquest bloc de text d'altlangs, quan s'<a href="/DDP/Interface_and_Features/EditURL/">edita una URL</a>, hi apareixen les subcategories d'altres idiomes per escollir-les a la llista desplegable 'Moure a una altra categoria'.</p>
      <p>Per exemple, si un editor d'una categoria de Pollastes reb un lloc web sobre pollastres que est en castell, pot consulktar la llista desplegable de la pantalla d'edici d'una URL, i si hi ha una categoria equivalent a <a href="http://dmoz.org/World/Espa%f1ol/">World/Espaol</a>, pot simplement seleccionar aquella categoria i envair el lloc web all. Alternativament, si no hi ha cap categoria en castell, pot cercar el bloc de text d'altlangs a la categoria superior per enllaar-hi a World/Espaol. If one existed, he 
    could forward the site to that category; otherwise he would repeat the process. 
  </p>
  <h3><a name="theory"></a>Altlang Theory - The Worldlinkerator and the Importance 
    of Reciprocality</h3>
  <p>Altlangs should always be reciprocal. That is to say, if category A altlang 
    links to category B, category B should also altlang link back to A. Not only 
    does this process enable the seamless traversal of categories in different 
    languages which was mentioned earlier, it also helps make the network of altlang 
    links potentially more comprehensive. </p>
  <p>The latter point deserves further explanation. A script has been written 
    called the <a href="http://dmoz.org:8080/Bookmarks/R/rpfuller/ODP/Tools/Worldlinkerator/">Worldlinkerator</a> 
    which, given a starting category, crawls altlang'd categories attempting to 
    produce a list of all categories that are equivalent but in different languages. 
    It then allows the user to update the relevant altlang blocks for the categories 
    crawled so as to increase their comprehensiveness. </p>
  <p>For example, consider <a href="http://dmoz.org:8080/Arts/">Arts/</a> . The Arts/ 
    category in German is <a href="http://dmoz.org:8080/World/Deutsch/Kultur/">World/Deutsch/Kultur</a> 
    . Imagine that the English category links to the German category, and nowhere 
    else. Then, imagine that the German category links to the Spanish Arts/ category 
    ( <a href="http://dmoz.org:8080/World/Espa%f1ol/Artes/">World/Espaol/Artes</a> 
    ). In this scenario, the altlang block for the English category is incomplete 
    -- it doesn't include Spanish. By running the Worldlinkerator on the English 
    category, the user would be informed of the existence of the Spanish category 
    and thus be able to link to it from Arts/ . This is because the tool would 
    find the link from Arts/ to World/Deutsch/Kultur (confirming that the latter 
    is equivalent to the former) and then would follow the link from World/Deutsch/Kultur/ 
    to World/Espaol/Artes (confirming that the latter is equivalent to the former). 
    Given the equivalency between the German and Spanish categories, it follows 
    that the Spanish category must also be equivalent to the English category. 
  </p>
  <p>As you may have noticed, for this process to be useful it is vital existing 
    altlangs being correct. If they are not, a user running the Worldlinkerator 
    -- even if they are doing so with due care -- is likely to exacerbate the 
    situation. Returning to our previous example, if Arts/ altlang'd to the French 
    equivalent of <a href="http://dmoz.org:8080/Computers/">Computers/</a> ( <a href="http://dmoz.org:8080/World/Fran%e7ais/Informatique/">World/Franais/Informatique</a> 
    ) then the program would assume that all of the altlangs from World/Franais/Informatique 
    pointed to categories equivalent to Arts/...</p>
  
<p> In an attempt to reduce the number of asymmetric altlangs, editor <a href="http://dmoz.org:8080/editors/profile.cgi?editor=sfromis">sfromis</a> 
  periodically generates a report detailing the discrepancies -- <a href="http://home1.inet.tele.dk/sfromis/BabelTower.html">the
