Public Interest Registry does not guarantee its accuracy. Users accessing the Public Interest Registry RDAP service agree to use the data only for lawful purposes, and under no circumstances may this data be used to: a) allow, enable, or otherwise support the transmission by e-mail, telephone, or facsimile of mass unsolicited, commercial advertising or solicitations to entities other than the registrar's own existing customers and b) enable high volume, automated, electronic processes that send queries or data to the systems of Public Interest Registry or any ICANN-accredited registrar, except as reasonably necessary to register domain names or modify existing registrations. When using the Public Interest Registry RDAP service, please consider the following: the RDAP service is not a replacement for standard EPP commands to the SRS service. RDAP is not considered authoritative for registered domain objects. The RDAP service may be scheduled for downtime during production or OT&E maintenance periods. Queries to the RDAP services are throttled. If too many queries are received from a single IP address within a specified time, the service will begin to reject further queries for a period of time to prevent disruption of RDAP service access. Abuse of the RDAP system through data mining is mitigated by detecting and limiting bulk query access from single sources. Where applicable, the presence of a [Non-Public Data] tag indicates that such data is not made publicly available due to applicable data privacy laws or requirements. Should you wish to contact the registrant, please refer to the RDAP records available through the registrar URL listed above. Access to non-public data may be provided, upon request, where it can be reasonably confirmed that the requester holds a specific legitimate interest and a proper legal basis for accessing the withheld data. Access to this data can be requested by submitting a request to WHOISrequest@pir.org. Public Interest Registry Inc. reserves the right to modify these terms at any time.

El dataset W3.CSS
Todos los sitios que hemos detectado utilizando W3.CSS, con versión, hosting, país, TLD y ranking de tráfico.
W3.CSS está presente en 2 datasets
La detección de W3.CSS forma parte de Technologies (€159/mes) y All data (€599/mes). Compre cualquiera de los dos para filtrar la lista completa de 13.065 sitios, o consiga antes una vista previa gratuita.
Acerca de W3.CSS
Los frameworks los suelen elegir los equipos. Este framework lo elige normalmente una sola persona, a menudo el mismo mes en que aprendió qué es una hoja de estilos, y esa historia de origen da forma a toda la población.
W3Schools lo publica como framework con licencia Open Source, disponible desde 2015 y escrito exclusivamente como CSS, sin ninguna dependencia de scripts. No hay paso de compilación, ni gestor de paquetes, ni archivo de configuración. Una sola etiqueta de enlace en la cabecera de un documento es la instalación entera, y la documentación reside dentro del sitio de tutoriales donde aprendió marcado una parte enorme de los desarrolladores autodidactas del mundo. El framework no compite por la adopción en organizaciones de ingeniería. Compite por el momento en que alguien necesita que una página parezca terminada para mañana.
La detección significa entonces algo bastante concreto. Un sitio que lo lleva fue montado, con una fiabilidad razonable, a mano y no generado, por una sola persona y no por un equipo, sin flujo de trabajo de frontend y sin presupuesto de frontend. La población llega hasta pequeños negocios de servicios, profesionales de oficios, clubes y asociaciones, colegios y departamentos, instituciones locales, páginas profesionales personales y proyectos en fase inicial. No son los sitios que aparecen en los rankings de tráfico, y son casi imposibles de enumerar por cualquier vía que no sea un rastreo completo.
Una nota de taxonomía antes de que nadie filtre por ella. Clasificamos el framework en la categoría UI frameworks, que es un artefacto de cómo creció el árbol de categorías y no una descripción del código. El framework no incluye ningún script, así que quien construya una lista de dependencias basadas en scripts debería excluirlo de forma explícita en lugar de heredarlo de la categoría.
La geografía añade un segundo eje y no un giro de guion. La mayor parte de lo que detectamos corresponde a Estados Unidos, con 5123, y la zona .com encabeza el reparto de dominios, cosa que sigue la costumbre de registrar en una zona genérica y no en una nacional.
El cruce de datos es lo que vuelve esto comercialmente interesante. Mire qué más se resolvió en esas mismas filas. Una parte significativa de estos sitios no lleva ningún gestor de contenidos, ni comercio electrónico, ni gestor de etiquetas, ni pila de marketing de ninguna clase, lo que en una web abrumadoramente generada los convierte en un segmento realmente insólito: escritos a mano, estáticos, sin gestión y casi con toda seguridad con la renovación pendiente desde hace tiempo. Los creadores de sitios web, los proveedores de alojamiento, las agencias y las empresas de marketing local quieren exactamente esa lista, y los auditores de accesibilidad la quieren por razones completamente distintas, porque el marcado hecho a mano falla en patrones en los que el marcado generado no falla.
No publicamos versión, y la razón es estructural. La hoja de estilos se descarga, se renombra y se sirve en local de forma rutinaria en lugar de enlazarse desde el sitio de quien la publica, lo que elimina tanto la marca de versión como, en muchos casos, el nombre de archivo del que depende nuestra detección. El recuento es, por tanto, una cota inferior. Los sitios que copiaron el archivo y lo renombraron usan el framework y faltan en nuestra población, y el error va siempre en esa única dirección.
