+10. Localization of user-facing content
+#######################################
+
+Status
+******
+
+Accepted
+
+Context
+*******
+
+.. note:: Terminology
+
+    * A "locale" is a specific language and region.
+      
+      E.g., Spanish is spoken in several locales: ``es-ar`` (Argentina),  ``es-mx`` (Mexico), ``es-es`` (Spain), etc.
+
+    * Internationalization (i18n) is the process of developing products that can be adapted to different languages and
+      cultures.
+
+    * Localization (l10n) is the process of adapting a product or content for a specific locale.
+
+
+Open edX is used worldwide. So for Aspects to be a fully-supported part of the Open edX ecosystem, it must at least
+support translations for user-facing content, page layout for left-to-right and right-to-left languages. It may also
+support localized representations of dates and calendars.
+
+Superset provides Aspect's user interface, and it supports a subset of locales for translating/displaying the menus and
+pages that the application serves. However, Superset does not translate its application or asset data, i.e. the
+dashboards and charts shown to users. Superset also has some open issues related to localization (e.g.  `issue#25258`_).
+
+Aspects must maintain and display translated versions of its supported Superset assets.
+
+Decision
+********
+
+* Aspects build process will support extracting user-facing content from Superset assets for translation, the production
+  of translated dashboards and charts, and synchronization of the latest translations to the project.
+* Normal Aspects users (non-superusers) will only see the dashboards and charts that match their preferred language as
+  selected in the LMS.
+* Open edX superusers using Aspects will see all translations of all Superset assets, so that they are able 
+* All Superset users may choose their preferred locale for Superset menus and pages from the "Languages" menu after
+  logging in; this will not be chosen automatically from their Open edX preferred language.
+* Aspects will contribute to Superset's i18n and l10n efforts where possible.
+
+Consequences
+************
+
+#. Aspects will configure Superset to run with a set of locales that best matches those locales Open edX supports.
+#. Aspects will create translated copies of all user-facing Superset assets (dashboards and charts).
+#. Access to these translated dashboards will be gated by role-based access controls (RBAC) using locale-specific roles.
+   Users are added to the locale-specific role that best matches their preferred language in Open edX, and so are
+   granted access to the appropriate translated dashboards and charts.
+#. Like other Open edX projects, translations for the Aspects project will be maintained in Transifex.
+#. Translations will be automatically synchronized using the Transifex Github App as per `OEP-58`_.
+
+Rejected Alternatives
+*********************
+
+**Translate assets on the fly with javascript**
+
+Another way to implement translations in the browser is using javascript and a mapping between English words/phrases and
+the translated words/phrases (e.g. `simple-translator`_). However, this approach cannot discern the context around how
+words/phrases are used, and so providing accurate translations for complex content can be difficult or impossible. This
+approach would also slow page load times and would provide a sub-standard user experience.
