I'm currently on (medical) leave of absence from Adobe: you can read about my brain implants for Parkinson's on my blog.
A good chunk of my career has been around Standards, especially (but not exclusively) for the Web. I would explain my job as "arguing about how the Internet should work".
What is a file format? A lot of my work has been in defining file formats, standards around them, protocols for negotiating formats for subsequent communication.
PDF, the Portable Document Format, was invented by Adobe folks more than 25 years ago--older than the web. Perhaps there are things we'd design differently today, but PDF is solid, widely deployed, and actively maintained. For some purposes, there's nothing like it. I'm helping with some related efforts:
- PDF and Open Data W3C Community Group established to document "best practices" for making data in PDF more accessible to simple processing using readily available tools.
- RFC8118: updated the registration of "application/pdf" primarily to show the "owner" is now ISO (International Standards Organization) and not Adobe. (also see GitHub repo).
- RFC7995: PDF Format for RFCs: The IETF is moving (slowly) to change its document format(s); IETF specs will be published in PDF and HTML (and XML), not just plain text. Note that the PDF file will include the XML as an attachment.
Metadata is data about data: e.g., for a phone call, who called whom when; for a library book, the card catalog information. There are different kinds of metadata, and different ways of associating metadata with the data it describes.

Computers around the world from different origins work with each other because everyone agrees how they should work. There's not a separate Internet for Google, Microsoft, Amazon, Adobe. But of course not everyone agrees; working out differences about the future is standards work.
