[Pandas-dev] Using a phrase "Similar to Pandas DataFrame" in other projects

[Marc Garcia]

In short:

1. You can use pandas without written consent for what in law is called
"fair use". Which for what you say is what you want to do, and other
projects do. The idea is that you can use the pandas "brand" to say "we are
compatible with pandas", "it's similar to a pandas dataframe"... But not
"we're the pandas consultancy", "we're pandas approved"... You can share
for "fair use" for more details.

2. If it's an open source project, and relevant to the pandas community,
just open a PR to be included in the Ecosystem page.

Thanks!
