version = {1.1}, < This is the version number of Visual-Meta

generator = {Author 7.0.1 (1020)}, < The name of the software which generated the Visual-Meta document (not necessarily the Visual-Meta itself, which may have been added by hand), including the version number (and build number in brackets if available)

vm-id-appended = {98765435678987654;reader(3.0)} < For documents which are already created (without Visual-Meta) where the reader software appends a vm-d for future reference. It is a hash of original PDF before Visual-Meta page is added, using a sha256 of the raw string value of the document, followed by the name and version of the software appending the vm-id.

plaintext = {name of document.txt or .html} < Name of document which has plain text of this document. No security presumed.

plaintext = {http : // ipfs.io/ipfs /bafkreidwyzsvsbxwwy6mqlf4} < Where a plaintext version of this PDF is accessible from (shown with fake URL to allow for rendering on this webpage in WordPress)

We are also considering https://nebulus.dev for IPFS hash for vm-id
