Subj3ct.com a exciting new resolution service for Subject Identifier has been launched yesterday. To help subj3ct gather more identifier the Topic Maps Lab decided to add a subj3ct support to their Atom Feed(s).

If you are using Ruby on Rails and a Topic Maps Engine you are welcome to copy’n’paste our builder atom code and participate in feeding the subj3ct :)

#Atom feed for people
xml.instruct!
xml.feed "xmlns" => "http://www.w3.org/2005/Atom" do
  xml.title   "Topic Maps Lab"
  xml.id      "/people"
  xml.updated Person.find(:last, :order => 'updated_at').updated_at.strftime 
         "%Y-%m-%dT%H:%M:%SZ"    #Atom always requires RFC 3339 format
  xml.author  { xml.name "Topic Maps Lab" }
  @people.each do |person|
    xml.entry do              
      xml.title   person.short_name
      xml.id    person.absolute_identifier
      xml.updated   person.updated_at.strftime("%Y-%m-%dT%H:%M:%SZ")
      xml.summary   person.project_involvment
      xml.link    "rel" => "SubjectIdentifier", "href" => person.absolute_identifier
      xml.link    "rel" => "SubjectRepresentation", "href" => person.absolute_identifier
      person.subject_identifiers.each do |si|
          xml.link    "rel" => "EquivalentIdentifier", "href" => si.reference
      end    
      xml.link    "rel" => "alternate", "href" => person.absolute_identifier #for valid Atom
    end
  end
end
