What the future holds

the site owner

Responsible for managing the creation, storage and distribution of content.

the content author

Responsible for researching, and creating the individual pieces of content

Two personas

the site owner

Responsible for managing the creation, storage and distribution of content.

the content author

Responsible for researching, and creating the individual pieces of content

don't waste my time

problems:

  1. When I create an entity I want to start with a sane default that already has all the schema.org RDFa mapping as well as the sane default Drupal formatters so that I don’t have to do this over and over for each individual field 
  2. When I build a site I want to start with a sane default content template so I don’t have to build every field, entity, relationship, and view from scratch

 

Content owner

more simply

  1. Give me a semantic entity template
  2. Give me a semantic content model template

don't make me think

don't break my flow

SOME BACKGROUND

RDFaCE: RDFa Content Editor 

mit fold demo

linked data tools demo

for Drupal 8

the future

never force authors to write markup

semantic tools in the wysiwyg

It should be the responsibility of a content management system to, as much as possible, interpret the intention of the author and structure the content accordingly

THE smart cms

take aways

  • Labor-saving tools for site builders and authors can be the catalyst for linked data
  • Drupal 8 now has the first level of tools for this
  • We will soon have more powerful tools
  • The future is a smart CMS in which more and more semantic meaning is inferred from the author by machine learning
