Some basic question about use iptc-xmp-fields for wordpress

Thanks for all your kind words and for the detailed description of your application. I am confident MLA can help you extract your metadata and get it to the right WordPress destinations. Your English is not bad at all – much better than my Schweizerdeutsch.

I looked at your site, which is beautiful, and analyzed a few of the image files. I see quite a bit of metadata in the files but I have not found an image that has a value in the Subject field. You wrote “The values are stored in this field with a separator ; but each value between two ; should be a Filter Tag (one keyword = one Filter Tag)“. If you could post a link or give me a way to find one or more files with the data values you want to extract I can give you more specific help.

I did find one file, inv-47.jpg, that has the location information and the description. The inv-43.jpg file also has “Sublocation”. The inv-52.jpg file also has location information in the “Adobe Photoshop Properties”.

I assume that when you write “Filter Tag” you mean you want to assign your keywords as terms in the WordPress “Tags” taxonomy or in MLA’s “Att. Tags” taxonomy. Let me know if I understand you correctly.

I will leave this topic unresolved and await your response; any additional details and example files you can provide will be very helpful. Thank you for your interest in the plugin.

Thank you for your update and for all the work you put in to preparing the screen shots; very helpful.

From your david1.jpg and david2.jpg screen shots it looks like “Filter Tag” is a custom taxonomy created by your theme or some plugin, separate from the taxonomies I mentioned in my earlier post. Is that right?

I believe the file shown in your david2.jpg screen shot is one of the files I downloaded from your site for analysis. I am confused because the metadata in the file I downloaded is different from that shown in your screen shot and in the examples you gave in your post. For example, the Title/Headline in the file I have is “Weinmesse Zug / Zugersee”. I do not see the “Weinmesse-Schiff auf dem Zugersee” shown in your screen shot. As I noted in my earlier post I do not see the “dc\subject” value in any of the files I examined.

Here is the relevant XMP metadata I found in the inv-52.jpg file. I have omitted some of the other data such as exif and tiff values:

As you can see, the naming conventions in the above data are somewhat different from the names in your post, e.g., {File.MD.XMP::photoshop\Headline\Headline\0} appears in my data as xmp:photoshop.Headline. In a similar way, {File.MD.XMP::iptcExt\LocationShownCity\LocationShownCity\0} is xmp:Iptc4xmpExt.LocationShown.0.Sublocation. You should be able to work out the other names from these examples.

For your information, here are the relevant IPTC fields populated in the file:

    '2#120' => 'Anliker, maschinen',

Based on the above I believe I can give you a start on mapping metadata to fields such as “Filter Tag”. I can’t test this unless you give me a specific file that contains the xmp:dc.subject value, but you can give this a try:

1. Go to the Settings/Media Library Assistant IPTC/EXIF tab.
2. If you want to apply the rule to new items as they are uploaded, check the “Enable IPTC/EXIF Mapping when adding new media” and “Enable IPTC/EXIF Mapping when updating media metadata” boxes.
3. Locate the “Filter Tag” rule entry in the table and click the “Edit” rollover action.
4. In the “IPTC Value” dropdown control leave the default “- None (select a value) -” in place.
5. In the “EXIF/Template Value” text box enter template:([+xmp:dc.subject+]).
6. In the “Priority” dropdown, select “EXIF”.
7. In the “Existing Text” dropdown, select “Replace” to replace existing term assignments or “Keep” to add the terms generated by the rule to any existing assignments.
8. In the “Option” dropdown, select “Array”.
9. In the “Delimiters” text box, enter “;” (semicolon).
10. Scroll down to the bottom of the screen and click “Update”.

Once you define a rule you can apply it to a single item, multiple items or all items:

• To map a single item, go to the Media/Assistant submenu and click the thumbnail of the item you want (or click the “Edit” rollover action) to get the Media/Edit Media screen. You can click the “Map IPTC/EXIF metadata” link to run your rules on this item, then scroll down and look at the “Att. Categories” meta box to inspect the results.
• To map two or more items, go to the Media/Assistant submenu and click the checkbox next to the items you want. Then, select “Edit” from the “Bulk Actions” dropdown above the checkboxes and click “Apply” to open the Bulk Edit area. Click the “Map IPTC/EXIF metadata” button to run your rules on the selected items.
• To map all of your items, stay on the Settings/Media Library Assistant IPTC/EXIF tab and click the “Execute” rollover action for the App. Categories rule. This may take a while.

I suggest template:([+xmp:dc.subject+]) because the parentheses around the substitution parameter will gracefully ignore files that do not contain a value in the field.

You can adapt the above instructions for your other fields, changing the template for each field:

• Title – template:([+xmp:photoshop.Headline+])
• ALT Text – template:([+xmp:photoshop.Headline+] copyright by SINUS)
• Description – template:([+xmp:Iptc4xmpExt.LocationShown.0.LocationShownCity+])(-[+xmp:Iptc4xmpExt.LocationShown.0.LocationShownProvinceState+])( - [+xmp:dc.Description+])

I hope the above instructions are clear enough to get you started. I will leave this topic unresolved for now in case you have problems or further questions regarding the assumptions I made and the suggested solutions.

Thanks for your kind words and for your update. Thanks as well for including a link to the Birger blog post, which I was not aware of. The blog post was created in 2015 and shows an older version of the MLA Settings pages, but the template information and other details should still be accurate.

I will leave this topic open and await good news on your further progress.

It has been a month since the last post in this topic. I hope you have found everything you need for your application.

I am marking this topic resolved, but please update it if you have problems or further questions regarding the metadata access suggestions in the earlier posts. Thanks for sharing your application details and for your interest in the plugin.
