I am constantly adding images to my genealogy database. The final destination of these images is the web. The annotation of these images is stored inside the image file itself. I use jpeg images and I annotate the images with RDFPic. RDFPic is a java application that stores metadate using the RDF (resource description framework) format in the comment section of the jpeg file. Unfortunately the program can handle only jpeg images and not tif or png images.

The easiest way is via OpenOffice. OpenOffice Draw can import EMF files and save as SVG. Other applications capable of opening EMF are FreeHand and CorelDraw (tested on Macintosh). However, FreeHand cannot export as SVG.
