and automatically update data from numerous documents and applications. For
example, a user might want to capture sales figures and totals from within a
spreadsheet and then include this information in a word-processing document
that summarizes sales for a given month. If both the spreadsheet and
by selecting data within the spreadsheet document and creating a publisher. The
spreadsheet application then writes a copy of that data to a separate file, called
an edition. The edition is represented by an icon; by default, it appears as the
icon shown in the first figure in Icon resources. If the user opens a
word-processing document and creates a subscriber to the spreadsheet
document's edition, the word-processing application then incorporates the
desired sales figures and totals from the spreadsheet document's edition into
the document.
If you want your application to publish or subscribe to data among its own
documents or among documents created by other applications that support the
editions, consider creating an icon that uniquely identifies your editions and
that associates them with your application's documents. See Icon resources
for information about creating icon resources. The file type for your edition
containers should be 'edtt' (for text-oriented data), 'edtp' (for
graphics-oriented data), or 'edts' (for sound-oriented data); and the creator,
of course, should be the signature of your application.
