Hey, thanks for the response.

For a bootstrapped, engineering-driven company like Ente, product offers the best leverage for growth. We are not P0-ing nested folders right now because we believe there are areas within the photos app investing into which will provide higher revenue returns, that we can re-invest into increasing our engineering bandwidth.

Now I understand the disappointment around us not prioritizing a feature that is blocking you from even using the product. It is a loss for all parties, but it is important for us to plan long-term. And while we're not prioritizing this specific feature, I don't think it is fair to say that we do not invest time into polish. We do care about our craft[0][1][2].

In case it helps, here's our product lead addressing the timelines for nested albums, and our perspectives around organization: https://www.youtube.com/watch?v=3lkTspvi_mM&t=367s

Thanks again for the YouTube link – I hadn't had time to watch the entire video yet, so I wasn't aware your product lead addressed nested folders specifically.

So how would nested tags interact with albums? Will I also be able to share (or contribute to) tags like I can share (or contribute to) albums? Actually, aren't albums already "tag-like" in the sense that photos can be assigned to multiple albums at the same time?

This was overly harsh, my apologies!

You will be able to create "smart albums" with nested tags, and share (and contribute) to them.

Albums are tag-like in the sense you described it, but might be an overkill[0] for the outcome we wish to achieve - organization, sharing, and ability to respect original folder structure when a user exports their data.

So if I understand you correctly, users will be able to share tags from a given album but you don't want to make tags separate collections (inside the existing album collection). But what is the alternative here if you want to secure access to the tags cryptographically (which I hope you do)?

A few thoughts:

1. Let's say files inside tags use the collection key of the parent album. Access to a tag (e.g. if I shared it with someone) therefore requires access to the collection key, thereby potentially exposing the entire album. (E.g. if a government agency got hold of a public link I've shared to a single tag inside a bigger album.) Bad.

2. Alternatively, let's say all file keys of files belonging to a tag will also be encrypted with an additional tag key (separately from the encryption with the collection key). This is certainly doable and I assume you already do a similar thing for photos belonging to multiple albums/collections. However, with nested tags this might get annoying fast if a file key needs to be encrypted not only with the tag key of the tag "foo/bar/baz" but also with the tag keys of "foo/bar" and "foo". If you wanted to avoid this, you'd encrypt the tag key of "foo/bar/baz" with the tag key of "foo/bar" and the latter with the tag key of "foo". But then isn't this more or less exactly what you would do if you implemented nested collections?

On top of this, you will need to store an encrypted map of tag -> tagged files somewhere both for performance reasons, for privacy reasons (if you stored the tags inside the files, you'd risk exposing them to people the tags weren't shared with), and to manage write access (contributions) to a tag.

All this, I assume, is also what you do for collections. So then, all in all, how different from collections would tags really be?

--

Irrespective of the encryption questions, wouldn't the addition of tags complicate your domain model quite a bit? You'd likely also need new API endpoints, and separate UIs for viewing photos belonging to a tag (as opposed to an album), sharing a tag, editing/renaming tags, …

[vishnukvmd]

The way I've thought about this, we will not have "files inside tags", but we will have tags (foo, bar, baz) attached to a file as additional encrypted metadata.

We have existing client-side infrastructure[0] that can create auto-updating albums based on metadata, and this can be extended to enable sharing workflows.

I'm not sure I understand yet. If tags (and the photos associated to them) are supposed to be shareable with others, how do you control read/write access to the tag if you don't use separate cryptographic keys? If you re-use/share existing keys (e.g. the parent album's collection keys), how do you ensure the recipients cannot read other photos or tag metadata not shared with them? What am I missing?

Once again thank you for taking the time to discuss this here! I appreciate it!

Happy to share my thoughts!

Current plan is to keep tags as part of an item's metadata, and allow sharing and access control with "smart albums" - that create a collection view over a tag-filter.

For eg. you can create a "smart album" for items that match the tags ["2020", "Holidays"]. Your devices will auto-add any items in your library that match these tags, to this collection. You can then share[0] this album with recipients who can view / add / auto-add items from their library.

Hope this makes sense!
