The "AFPResources" page has been changed by Harry Lewis:

   * Image Object Content Architecture (IOCA), which is used to represent image information such as scanned pictures.  
   * Presentation Text Object Content Architecture (PTOCA), which is used to define text information. ''End Quote''

+ To generate MO``:DCA documents (datastreams in the AFP language) one needs the relevant specifications. Here is how to get them:
+  * Go to http://www.afpcinc.org
+  * Click on the Publications tab
+  * The most recent MO``:DCA, IPDS and other references are free and downloadable in PDF format.
-  * Goto http://www.elink.ibmlink.ibm.com/public/applications/publications/cgibin/pbi.cgi
-  * Select your Country
-  * Click on Search for publications
-  * Enter "MO``:DCA" in the Search On box, or enter publication reference SBOF-6179-00 for all of the AFP Architecture Manuals (IPDS, BCOCA, FOCA, GOCA, IOCA, PTOCA, MODCA) and click GO.
-  * The first document listed should be the most recent MO``:DCA reference which is downloadable in PDF format.
  
- From there its easy to get the rest. Open the PDF and in the section Related Publications the other relevant specifications are listed. Search for them on the above mentioned web site by Order Number and download them one by one.
+ For those who don't have access to an IBM AFP environment it is very difficult to verify the correctness of any generated MO``:DCA document. The AFP Consortium provides a validator tool to Members for AFP Interchange Set 3. Information for joining the AFPC is available on the website.

   * The AFP Viewer Internet Explorer plug-in allows viewing of .afp in your browser. It can be found by going to http://www.ibm.com and then enter "AFP Viewer" into the Search box at the top. The first returned result should point to a page from where the viewer can be downloaded.

  When implementing AFP features it's a very good idea to use the most simple methods available. For example, for bi-level bitmap images, it's best to use the FS10 function set. Or if you want to reduce print file size or improve printing performance, images should not be included as image objects (because Include Object IOB is not available everywhere). Instead, page segments should be used even if that means that you have to embed the same image twice if it needs to be printed in two different sizes (because Include Page Segment IPS doesn't support scaling). But that has another advantage: you can make use of hard page segments which allows to transfer images to the printer separately, thus conserving bandwidth and processing power in the print processor.
  
+ In 2009 AFP transitioned to an open standard managed by the AFP Consortium http://www.afpcinc.org. In August 2011 a new "Interchange Set" (IS/3) was defined which excludes some outdated resources which have been replaced by updated technology (e.g. FOCA bit map fonts replaced by TrueType / OpenType). Many shipping components, such as print servers and printers, will continue to receive and handle legacy AFP datastream but generators are encouraged to transition to IS/3 for improved overall interoperability.
