Searchable Archives of digital content

I know some in the artist communities i’m striving to support on their initiative to be in the drivers seat of their digital content(music, images, books, docs…etc) and the sharing of it. Initially I was thinking nextcloud however they are seeking ways to have a paid membership to access content. Do you all know of any open source tools that may support their needs or orgs that may be into building a tool like this or even existing proprietary software that I could look up alternatives to??
Someone mentioned to me to look into and IPFS so I’m doing some research there
Thanks in advance :slight_smile:
