I need Indesign macro to export and import alt text.

This is not a simple task, Sandeep. I am sure it can be done with a script, but do you have a budget to pay someone to write it? What format do you want the text in? One long txt file? Or many txt files? A CSV file?

Is the alt text included in an IDML file? Do you need the remaining text translated also (i.e. the text that isn’t alt text) ?
Most translators can use IDML as an exchange format for their CAT (computer aided translation) tools.

Chris.

Edit: answering my own question – apparently IDML isn’t an option:
I set up a test file, and my alt text didn’t appear in Wordfast Pro (the CAT tool that I use).
Plus, this link :
https://www.proz.com/forum/sdl_trados_support/275228-sdl_trados_studio_2014_cannot_extract_alt_text_in_idml_files.html
appears to suggest that Trados (the most widely-used CAT tool) doesn’t see the text either.

Hmm, interesting.
I’ve just created a test file with alt text on and object, and exported to IDML. I then opened up the IDML (which is just a zipped archive of XML files), to look through with a text editor.
The alt text IS in fact in the IDML file, under Spreads.

In my very simple sample it was in a file called Spread_uc3.xml, and in a section of XML like this:

<ObjectExportOption AltTextSourceType=”SourceCustom” ActualTextSourceType=”SourceXMLStructure” CustomAltText=”Alt text added in the dialog” CustomActualText=”$ID/” ApplyTagType=”TagFromStructure” CustomImageConversion=”false” ImageConversionType=”JPEG” CustomImageSizeOption=”SizeRelativeToPageWidth” ImageExportResolution=”Ppi300″ GIFOptionsPalette=”AdaptivePalette” GIFOptionsInterlaced=”true” JPEGOptionsQuality=”High” JPEGOptionsFormat=”BaselineEncoding” ImageAlignment=”AlignLeft” ImageSpaceBefore=”0″ ImageSpaceAfter=”0″ UseImagePageBreak=”false” ImagePageBreak=”PageBreakBefore” CustomImageAlignment=”false” SpaceUnit=”CssPixel” CustomLayout=”false” CustomLayoutType=”AlignmentAndSpacing”>

The alt text that I added is “Alt text added in the dialog” which appears under CustomAltText=”Alt text added in the dialog”

So it would appear that the filters used by our CAT tools aren’t picking this up as potentially-translatable text.

I wonder if the open source OmegaT with those Okapi filters would be configurable to do this? Sorry, but I don’t have the time or tech knowledge to test this.

Good luck,
Chris
