How to embed EXIF data with Schema correctly

Hello!
I mean with the question, whether  there are possibilities to make a shorter notation as to write each EXIF property in an extra line? 

<div itemscope itemtype="http://schema.org/ImageObject">
<div itemprop="representativeOfPage">
<img alt="" src="data:image/jpeg;base64,/9j/4AAQSkZJRgABAgAAZABkAAD" />

<meta itemprop="exifData" content="Resolution : 600 x 445" />
<meta itemprop="exifData" content="Jpeg process : Progressive" />
</div>
</div>
