VM Boilerplate text Sept 2021

The data below is what we call Visual-Meta. It is an approach to add information about a document to the document itself, on the same level of the content (in style of BibTeX). ¶ It is very important to make clear that Visual-Meta is an approach more than a specific format and that it is based on wrappers. Anyone can make a custom wrapper for custom metadata and append it by specifying what it contains: for example @dublin-core or @rdfs. ¶ The way we have encoded this data, and which we recommend you do for your own documents, is as follows: ¶ When listing the names of the authors, they should be in the format ‘last name’, a comma, followed by ‘first name’ then ‘middle name’ whilst delimiting discrete authors with (‘and’) between author names, like this: Shakespeare, William and Engelbart, Douglas C. ¶ Dates should be ISO 8601 compliant. ¶ Every citable document will have an ID which we call ‘vm-id’. It starts with the date and time the document’s metadata/Visual-Meta was ‘created’ (in UTC), then max first 10 characters of document title. ¶ To parse the Visual-Meta, reader software looks for Visual-Meta in the PDF by scanning the document from the end, for the tag @{visual-meta-end}. If this is found, the software then looks for @{visual-meta-start} and uses the data found between these tags. This was written September 2021. More information is available from for as long as we can maintain the domain.
