1. How Omeka S’s Translation System Works

Omeka S uses gettext, a standard translation system. In this system:

  • .po files: Human-readable translation source files
  • .mo files: Compiled binary files (actually used)
  • $translate() function: Applies translations within PHP templates

2. Files Required for Theme Multilingual Support

Required Directory Structure

3. Step-by-Step Guide

Step 1: Configuring theme.ini

Add the following line to the [info] section of the config/theme.ini file:

[nvadohiaeuemanmrtsesfeshck_oiorat]=ori_rnpva"=tenY=irso"oslu"Yniar1oot.u=niT0r_oh."cne0NTosm"ahnemes=emtN"er"aatmdireenu"stec"r=ip"#t^i4o.n1T".h0i"slineisimportant!

Warning: Without has_translations = "true", translation files will not be loaded.

Step 2: Creating Translation Files

2.1 Creating the PO File

Create language/ja.po:

mm"""""""""""#mmmmmm#mmmmmmssPRPPLLLMCCPssssssssssssggreOOaaaIoolNggggggSggggggisopT-snnMnnuaisisiseisisisdtjo-RtggEttrvdtdtdtadtdtdtrerCe-uu-eeairrrrrrr"ctrvTaaVnnlg"""c"""""t-eirggett-aH"B"S"hN"%"i""-Masaeer--Ftoreo1%tIstin-:sTToimoar$1edgiosTiyrroew"r"eRd$m-ionlejopamn""scsedsVdn-aaanensehus%%"e--Dtm\::s:""lu22rBDao:nftl$$"suatr"1tenstssigte:J.erps""ose:a0x-ln-:Yp\tEuF":T2oan/nroo20un"pcauY:02reloln25sadsdu5-Neii="rn-0a\nn1"01mn;g;T1-e":h-1\cpe13nh8lm3"abue1rir12staN2:e\la:0tn=m00="0e0+U;\+0T\n09Fn"90-"0080\\\nnn"""

2.2 Compiling the MO File

Compile the PO file into an MO file:

#####msIMUCCgnabeofscunmmt:ntptatOilbuSllr//eieDRnweHlgbEaiiLnmna:gssnugt:safaugmlsdetluo/djcgoyaoeu.mtammmtpoaetinx-nldtgsaetn(tagilufilangnsgeete/eatjdltaele.dxp)gtoettext

Step 3: Using Translations in Templates

Usage in PHP Templates

4. Common Mistakes and Solutions

Mistake 1: Creating Module.php

claUsnsneMcoedsuslaerye!xtNeontdsneAebdsetdrafcotrMotdhuelmees{}

Solution: Module.php is not needed for themes. has_translations = "true" alone is sufficient.

Mistake 2: Case Mismatch

mm<ss?gg=PisPOdtH$rPtf"riG"talreneimsdpl"la"attee('grid')?>Won'twork!

Solution: Translation keys are case-sensitive. Make sure they match exactly.

Mistake 3: Incorrect Language Code

6. Troubleshooting

Checklist When Translations Are Not Applied

  1. Check theme.ini
[nvadohiaeuemanmrtsesfeshck_oiorat]=ori_rnpva"=tenY=irso"oslu"Yniar1oot.u=niT0r_oh."cne0NTosm"ahnemes=emtN"er"aatmdireenu"stec"r=ip"#t^i4o.n1T".h0i"slineisimportant!

1 2. Check MO file

[nvadohiaeuemanmrtsesfeshck_oiorat]=ori_rnpva"=tenY=irso"oslu"Yniar1oot.u=niT0r_oh."cne0NTosm"ahnemes=emtN"er"aatmdireenu"stec"r=ip"#t^i4o.n1T".h0i"slineisimportant!

2 3. Clear cache

 * Browser: Ctrl+Shift+R (Windows/Linux), Cmd+Shift+R (Mac)
 * When using Docker: Restart the container

3 4. Check language settings

 * Omeka S admin panel -> Site settings -> Set language to "Japanese"
 * User settings -> Set language to "Japanese"

Summary

Multilingual support for Omeka S themes can be achieved in the following three steps:

  1. Add has_translations = "true" to theme.ini
  2. Place translation files in the language/ directory
  3. Use the $translate() function in templates

Module.php and module.config.php are not needed, and multilingual support can be achieved with simple configuration.
