Open-Xchange Publishing

Publishing Data with Open-Xchange

Open-Xchange offers to publish an increasing amount of internal data like contacts, documents, appointments. This data can be published in a way that it is machine-readable using OXMF and it can be customized in it's look and feel using common web techniques like CSS.

Open-Xchange is using the FreeMarker Template Engine to export the internal date to the published templates. Check the FreeMarker Manual on how to use it.

Open-Xchange Internal data structures to access with FreeMarker

Contacts

Within freemarker, you are given a list called contacts, which contains all contacts of the given publication. This is the central element of the publication. Freemarker enables you to access every attribute of the class Contact that has both a setter and a getter. See the JavaDoc for the class to find out about attributes or use the example template of your OX.

Example for Contacts

This is the basic loop over the list of contacts that you get:

  <#list contacts as contact>
     <div class="ox_contact">
        <span class="ox_company">$contact.company</span>
        <span class="ox_company">$contact.uRL</span>
        <span class="ox_note">$contact.note</span>
     </div>
  </#list>

Infostore

You are given a list called infostore, which contains all infostore items of the given publication. This is the central element of the publication. Freemarker enables you to access every attribute of the class Infostore that has both a setter and a getter. See the JavaDoc for the class to find out about attributes or use the example template of your OX.

Example for Infostore

  <#list infostore as infoitem>
     <div class="an_infoitem">
        <span key="ox_title">$infoitem.title</span>
        <span key="ox_url">$infoitem.URL</span>
        <span key="ox_title">$infoitem.version</span>
        <span key="ox_creationDate">$infoitem.creationDate</span>
        <span key="ox_lastModified">$infoitem.lastModified</span>
        <span key="ox_comment">$infoitem.description</span>
     </div>
  </#list>

Calendar

The calendar is a bit trickier than the others, because appointments can be recurring series with exceptions. So their data structure is a bit more complicated. That is why there is currently no Publish/Subscribe system in place, the freemaker templating is just used to render print views. There are two approaches to render the calendar.

Printing the text-processor way

The first approach uses a text-processor style: Your are given a list of appointments (all non-recurring, they have been broken up for you already) sorted by start date and a list of formatting information (like "between appointment 1 and 2 starts a new day"). You are free to ignore most of the formatting information (if you want to make a plain list of appointments, for example).

Variables for calendar printing

Variable	Description	appointments	A list of appointments, all single day appointments with no recurrence information, sorted by starting date.
formattingInfo	A list of formatting information, each entry containing a position (position zero is before the first appointment) and a flag that explains what it marks.

Formatting information:

Constant	Description	"0"	Day break: Following appointment starts on a new day
"1"	Week break: Following appointment starts on a new week
"2"	Month break: Following appointment starts on a new month
"3"	Year break: Following appointment starts on a new year
"10"	Day name: This element contains the name of the new day
"11"	Fill day: Place holder if the list covers a day that as no appointment in there (so you do not have to guess when to place fillers in more complex designs)

Additional fields for all publications

These fields are contained within all publication templates, independent of the type.

Variable	Description
publication	The complete publication object.
request	The http request that was sent to show this publication.
dateFormat	The format of the date, usually in the java.text.SimpleDateFormat.
timeFormat	Like date format, just for displaying times during the day (without the year, month or day).
privacy	The privacy text meant to be published on the displayed page (*).
userContact	The contact that is responsible for the publication of this page (*).

(*) Note: Several countries legally require you to publish this information. Leave it out at your own peril.

Changing the default templates

The default templates of all existing items to publish can be found in the folder /opt/open-xchange/templates/ of every Open-Xchange installation, if the package open-xchange-publish-microformats is installed:

$ dpkg -L open-xchange-publish-microformats | grep templates
/opt/open-xchange/templates
/opt/open-xchange/templates/contacts_oxmf_uncensored.tmpl
/opt/open-xchange/templates/infostore.tmpl
/opt/open-xchange/templates/contacts_hcard_censored.tmpl
/opt/open-xchange/templates/contacts_oxmf_censored.tmpl
/opt/open-xchange/templates/contacts.tmpl
/opt/open-xchange/templates/contacts_hcard_uncensored.tmpl

When these files are changed, new published items in Open-Xchange will get this look and feel. Check out the online help or the user guides on how to publish using Open-Xchange.
