ARCA del Mar Caribe is a WordPress plugin that turns your site into a local ARK resolver for the slash form `/ark:/NAAN/name/qualifier`. Plugin owner and copyright holder: **Editorial Mar Caribe**. Unlike a plain redirect, the resolver can keep the ARK identifier in the browser address bar while displaying the target resource inside an iframe. It can also issue a standards-based HTTP 302 or 303 redirect. **Features** * Public resolver rules for `/ark:/NAAN/name` and `/ark:/NAAN/name/qualifier`. * Two delivery modes per identifier: embedded viewer (the address bar keeps the ARK) or HTTP 302/303 redirect. * Admin screen under Settings > ARCA del Mar Caribe to add, edit and delete identifiers. * Edit action that changes an existing identifier’s destination URL and delivery mode without altering its NAAN, name or qualifier. * Validation for NAAN (five digits), assigned name and qualifier segments. * Destination URLs restricted to http and https. * Canonical redirects disabled for ARK requests so the identifier is preserved. * No external services, trackers or remote requests. * Uninstall removes the stored identifiers. #### Español ARCA del Mar Caribe convierte un sitio WordPress en un resolvedor local de identificadores ARK en la forma de barra `/ark:/NAAN/nombre/cualificador`. Permite mantener la URL ARK en la barra del navegador mostrando el recurso en un iframe, o redirigir con HTTP 302/303. Los identificadores se gestionan desde Ajustes > ARCA del Mar Caribe. Cada registro existente dispone de una acción **Editar URL** que permite cambiar el destino y el modo de entrega sin modificar el NAAN, el nombre ni el cualificador. Características: reglas públicas para las dos variantes de ruta, validación de NAAN y segmentos, URLs limitadas a http/https, formulario con nonces y comprobación de permisos, edición del destino de un ARK ya creado, assets cargados solo en la pantalla del plugin y limpieza de datos al desinstalar. ## Installation 1. Upload the `arca-del-mar-caribe` folder to `/wp-content/plugins/`, or install the ZIP from _Plugins > Add New > Upload Plugin_. 2. Activate the plugin through the _Plugins_ screen. 3. Go to _Settings > Permalinks_ and save the settings once so the ARK rewrite rules are registered. 4. Go to _Settings > ARCA del Mar Caribe_ and add your identifiers. #### Manual installation Extract `arca-del-mar-caribe.zip` and upload the resulting `arca-del-mar-caribe` folder to `/wp-content/plugins/`. Do not nest it inside another folder with the same name. ## FAQ ### Which permalink structure is required? A pretty permalink structure is required (for example `/%postname%/`). The ARK rules are rewrite rules and do not work with the “Plain” permalink option. ### Why does the ARK URL return a 404? Check that the permalink structure is not “Plain”, that the plugin was activated after the rules were added, and that the NAAN, name and qualifier match the stored record exactly. Saving the Permalinks screen once flushes the rules. ### The embedded view is blank or shows an error Some sites send `X-Frame-Options` or `Content-Security-Policy` headers that block embedding. In that case edit the identifier and choose the HTTP redirect mode instead. ### Are redirects cached? No. ARK responses send no-cache headers so changes in the target URL take effect immediately. ### Does it support multi-segment ARK suffixes? This version supports one optional qualifier segment after the name (`/ark:/NAAN/ name/qualifier`). Additional suffix segments are not resolved. ### How do I change the destination URL of an existing ARK? Go to _Settings > ARCA del Mar Caribe_, click _Editar URL_ in the row of the identifier, update the URL and save. The NAAN, name and qualifier stay unchanged; only the destination and the delivery mode are updated. ### Is the destination URL checked? The URL must use http or https. Only users with the `manage_options` capability can create or edit identifiers, and the destination is stored by the administrator, never supplied by the visitor. Because the plugin is a public resolver, the destination may point to an external host. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “ARCA del Mar Caribe” is open source software.
