The Plus Coalition is an international non-profit organization dedicated to a mission: “to enable access to and understanding of information about visual artworks for the benefit of its members and the general public.”
As part of their work, they define the PLUS XMP namespace, which provides fields available for optional use in embedding and reading image license metadata in digital files and other documents. The PLUS namespace is supported by IMatch and ExifTool.
The PLUS DataMining Tag
While the PLUS namespace is typically not relevant for enthusiast or non-commercial photographers, one XMP tag named PLUS::XMP\DataMining\DataMining
could be beneficial. This tag becomes particularly useful if you frequently upload your images to photo-sharing websites, social networks, competitions, and similar platforms.
PLUS defines several possible values for this tag, to express data mining prohibition or permission, optionally with constraints.
Using the PLUS DataMining Tag in IMatch
To use this tag in IMatch, you just include it in a standard or custom Metadata Panel layout.

You can now select one of the predefined values easily and apply it to all selected files.

If you upload images with an embedded PLUS DataMining value, you at least clearly specify which uses of your images are permitted for data mining and AI purposes. Whether search engines and AI bots honor these permissions is another matter, often depending on local laws, regulations, and the policies of the respective companies.
The PLUS DataMining Tag in Combination with IPTC Metadata
The IPTC defines a set of similar tags, which can be used in combination with PLUS DataMining to specify additional machine-readable data. If you use these, you set the PLUS DataMining tag to the corresponding iptcExt: value available for PLUS DataMining.
Tip: Add Watermarks with the IMatch Batch Processor
To safeguard your images against unauthorized use, such as copying or repurposing, utilize the IMatch Batch Processor. This tool allows you to overlay images and text onto your photos, deterring others from copying or reusing them without proper attribution. Additionally, this method may complicate AI’s ability to replicate your images.

Conclusion
In conclusion, as digital images become increasingly integral to our online presence and interactions, safeguarding your creative work from unauthorized data mining and AI exploitation is essential. The PLUS Coalition’s DataMining tag offers photographers a practical tool for asserting control over how their images are used across various platforms. By embedding these metadata tags into your files using tools like IMatch, you not only specify permissible uses but also contribute to a broader effort in protecting visual content rights.
While the effectiveness of these permissions may vary based on legal frameworks and platform policies, taking this step is a proactive measure that underscores your commitment to protecting intellectual property. Coupling the PLUS DataMining tag with IPTC standards further enhances this protective layer, ensuring comprehensive metadata coverage. As creators continue to navigate the complex digital landscape, tools like those developed by the PLUS Coalition serve as vital allies in preserving the integrity and intended use of visual artworks.
