+# NIP-XX: Place Photos and Media
+
+`draft` `optional`
+
+## Abstract
+
+This NIP defines a standardized event format for sharing photos, videos, and other visual media tied to specific real-world locations (e.g., OpenStreetMap POIs).
+
+While NIP-68 (Picture-first feeds) caters to general visual feeds, this NIP specifically targets map-based applications, travel logs, and location directories by mandating strict entity identifiers (`i` tags) and spatial indexing (`g` tags).
+
+## Event Kind
+
+`kind: 360`
+
+## Content
+
+The `.content` of the event SHOULD generally be empty. If a user wishes to provide a detailed description, summary, or caption for a place, clients SHOULD encourage them to create a Place Review event (`kind: 30360`) instead.
+
+## Tags
+
+This NIP relies on existing Nostr tag conventions to link media to places and provide inline metadata.
+
+### Required Tags
+
+#### 1. `i` — Entity Identifier
+
+Identifies the exact place the media depicts using an external identifier (as defined in NIP-73). OpenStreetMap data is the default:
+
+```json
+["i", "osm:node:123456"]
+```
+
+- For OSM POIs, `<type>` MUST be one of: `node`, `way`, `relation`.
+
+#### 2. `g` — Geohash
+
+Used for spatial indexing and discovery. Events MUST include at least one high-precision geohash. To optimize for map-based discovery across different zoom levels, clients SHOULD include geohashes at multiple resolutions:
+
+```json
+["g", "thrr"]        // coarse (~city)
+["g", "thrrn5"]      // medium (~1km)
+["g", "thrrn5k"]     // fine (~150m)
+["g", "thrrn5kxyz"]  // exact
+```
+
+#### 3. `imeta` — Inline Media Metadata
+
+An event MUST contain exactly one `imeta` tag representing a single media item. The primary `url` SHOULD also be appended to the event's `.content` for backwards compatibility with clients that do not parse `imeta` tags.
+
+Clients SHOULD include `alt` (accessibility descriptions), `dim` (dimensions), `m` (MIME type), and `blurhash` where possible.
+
+```json
+[
+  "imeta",
+  "url https://example.com/photo.jpg",
+  "m image/jpeg",
+  "dim 3024x4032",
+  "alt A steaming bowl of ramen on a wooden table at the restaurant.",
+  "blurhash eVF$^OI:${M{o#*0-nNFxakD-?xVM}WEWB%iNKxvR-oetmo#R-aen$"
+]
+```
+
+### Optional Tags
+
+- `t`: Hashtags for categorization (e.g., `["t", "food"]`, `["t", "architecture"]`).
+- `content-warning`: If the media contains NSFW or sensitive imagery.
+- `published_at`: Unix timestamp of when the photo was originally taken or published.
+
+## Example Event
+
+```json
+{
+  "id": "<32-bytes hex>",
+  "pubkey": "<32-bytes hex>",
+  "created_at": 1713205000,
+  "kind": 360,
+  "content": "",
+  "tags": [
+    ["i", "osm:node:987654321"],
+    ["g", "xn0m"],
+    ["g", "xn0m7h"],
+    ["g", "xn0m7hwq"],
+
+    [
+      "imeta",
+      "url https://example.com/ramen.jpg",
+      "m image/jpeg",
+      "dim 1080x1080",
+      "alt A close-up of spicy miso ramen with chashu pork, soft boiled egg, and scallions.",
+      "blurhash UHI=0o~q4T-o~q%MozM{x]t7RjRPt7oKkCWB"
+    ],
+
+    ["t", "ramen"],
+    ["t", "food"]
+  ]
+}
+```
+
+## Rationale
+
+### Why not use NIP-68 (Picture-first feeds)?
+
+NIP-68 is designed for general-purpose social feeds (like Instagram). Place photos require strict guarantees about what entity is being depicted to be useful for map clients, directories, and review aggregators. By mandating the `i` tag for POI linking and the `g` tag for spatial querying, this kind ensures interoperability for geo-spatial applications without cluttering general picture feeds with mundane POI images (like photos of storefronts or menus).
+
+### Separation from Place Reviews
+
+Reviews (kind 30360) and media have different lifecycles and data models. A user might upload 10 photos of a park without writing a review, or write a detailed review without attaching photos. Keeping them as separate events allows clients to query `imeta` attachments for a specific `i` tag to quickly build a photo gallery for a place, regardless of whether a review was attached.
+
+### Single Photo per Event
+
+Restricting events to a single `imeta` attachment (one photo per event) is an intentional design choice. Batching photos into a single event forces all engagement (likes, zaps) to apply to the entire batch, rendering granular tagging and sorting impossible. Single-photo events enable per-photo engagement, fine-grained categorization (e.g., tagging one photo as "food" and another as "menu"), and richer sorting algorithms based on individual photo popularity.

+# NIP-XX: Place Reviews
+
+`draft` `optional`
+
+## Abstract
+
+This NIP defines a standardized event format for decentralized place reviews using Nostr. Reviews are tied to real-world locations (e.g. OpenStreetMap POIs) via tags, and include structured, multi-aspect ratings, a binary recommendation signal, and optional contextual metadata.
+
+The design prioritizes:
+
+- Small event size
+- Interoperability across clients
+- Flexibility for different place types
+- Efficient geospatial querying using geohashes
+
+## Event Kind
+
+`kind: 30360`
+
+## Tags
+
+Additional tags MAY be included by clients but are not defined by this specification.
+
+This NIP reuses and builds upon existing Nostr tag conventions:
+
+- `i` tag: see NIP-73 (External Content Identifiers)
+- `g` tag: geohash-based geotagging (community conventions)
+
+Where conflicts arise, this NIP specifies the behavior for review events.
+
+### Required
+
+#### `i` — Entity Identifier
+
+Identifies the reviewed place using an external identifier. OpenStreetMap data is the default:
+
+```
+["i", "osm:<type>:<id>"]
+```
+
+Requirements:
+
+- For OSM POIs, `<type>` MUST be one of: `node`, `way`, `relation`
+
+Examples:
+
+```
+["i", "osm:node:123456"]
+["i", "osm:way:987654"]
+```
+
+### Geospatial Tags
+
+#### `g` — Geohash
+
+Geohash tags are used for spatial indexing and discovery.
+
+##### Requirements
+
+- Clients MUST include at least one high-precision geohash (length ≥ 9)
+
+##### Recommendations
+
+Clients SHOULD include geohashes at the following resolutions:
+
+- length 4 — coarse (city-scale discovery)
+- length 6 — medium (default query level, ~1 km)
+- length 7 — fine (neighborhood, ~150 m)
+
+Example:
+
+```
+["g", "thrr"]
+["g", "thrrn5"]
+["g", "thrrn5k"]
+["g", "thrrn5kxyz"]
+```
+
+##### Querying
+
+Geospatial queries are performed using the `g` tag.
+
+- Clients SHOULD query using a single geohash precision level per request
+- Clients MAY include multiple geohash values in a filter to cover a bounding box
+- Clients SHOULD limit the number of geohash values per query (e.g. ≤ 30)
+- Clients MAY reduce precision or split queries when necessary
+
+Note: Other queries (e.g. fetching reviews for a specific place) are performed using the `i` tag and are outside the scope of geospatial querying.
+
+## Content (JSON)
+
+The event `content` MUST be valid JSON matching the following schema.

+
+## Semantics
+
+### Ratings
+
+- Scores are integers from 1 to 10
+- `quality` is required and represents the core evaluation of the place
+- Other fields are optional and context-dependent
+
+### Aspects
+
+- Free-form keys allow domain-specific ratings
+- Clients MAY define and interpret aspect keys
+- Clients SHOULD reuse commonly established aspect keys where possible
+
+## Recommendation Signal
+
+The `recommend` field represents a binary verdict:
+
+- `true` → user recommends the place
+- `false` → user does not recommend the place
+
+Clients SHOULD strongly encourage users to provide this value.
+
+## Familiarity
+
+Represents user familiarity with the place:
+
+- `low` → first visit or limited exposure
+- `medium` → occasional visits
+- `high` → frequent or expert-level familiarity
+
+Clients MAY use this signal for weighting during aggregation.
+
+## Context
+
+Optional metadata about the visit.
+
+- `visited_at` is a Unix timestamp
+- `duration_minutes` represents time spent
+- `party_size` indicates group size
+
+## Interoperability
+
+This specification defines a content payload only.
+
+- In Nostr: place identity is conveyed via tags
+- In other protocols (e.g. ActivityPub, AT Protocol): identity MUST be mapped to the equivalent field (e.g. `object`)
+
+Content payloads SHOULD NOT include place identifiers.
+
+## Rationale
+
+### No Place Field in Content
+
+Avoids duplication and inconsistency with tags.
+
+### Multi-Aspect Ratings
+
+Separates concerns (e.g. quality vs service), improving signal quality.
+
+### Recommendation vs Score
+
+Binary recommendation avoids averaging pitfalls and improves ranking.
+
+### Familiarity
+
+Provides a human-friendly proxy for confidence without requiring numeric input.
+
+### Geohash Strategy
+
+Multiple resolutions balance:
+
+- efficient querying
+- small event size
+- early-stage discoverability
+
+## Future Work
+
+- Standardized aspect vocabularies
+- Reputation and weighting models
+- Indexing/aggregation services
+- Cross-protocol mappings
+
+## Security Considerations
+
+- Clients SHOULD validate all input
+- Malicious or spam reviews may require external moderation or reputation systems

+# Ranking Algorithm
+
+Your inputs:
+
+- many users
+- partial ratings
+- different priorities
+
+Your output:
+
+> “Best place _for this user right now_”
+
+---
+
+## Step 1: Normalize scores
+
+Convert 1–10 → 0–1:
+
+```text
+normalized_score = (score - 1) / 9
+```
+
+Why:
+
+- easier math
+- comparable across aspects
+
+---
+
+## Step 2: Per-aspect aggregation (avoid averages trap)
+
+Instead of mean, compute:
+
+### A. Positive ratio
+
+```text
+positive = score >= 7
+negative = score <= 4
+```
+
+Then:
+
+```text
+positive_ratio = positive_votes / total_votes
+```
+
+---
+
+### B. Confidence-weighted score
+
+Use something like a **Wilson score interval** (this is key):
+
+- prevents small-sample abuse
+- avoids “1 review = #1 place”
+
+---
+
+## Step 3: Build aspect scores
+
+For each aspect:
+
+```text
+aspect_score = f(
+  positive_ratio,
+  confidence,
+  number_of_reviews
+)
+```
+
+You can approximate with:
+
+```text
+aspect_score = positive_ratio * log(1 + review_count)
+```
+
+(Simple, works surprisingly well)
+
+---
+
+## Step 4: User preference weighting
+
+User defines:
+
+```json
+{
+  "quality": 0.5,
+  "value": 0.2,
+  "service": 0.2,
+  "speed": 0.1
+}
+```
+
+Then:
+
+```text
+final_score = Σ (aspect_score × weight)
+```
+
+---
+
+## Step 5: Context filtering (this is your unfair advantage)
+
+Filter reviews before scoring:
+
+- time-based:
+  - “last 6 months”
+
+- context-based:
+  - lunch vs dinner
+  - solo vs group
+
+This is something centralized platforms barely do.
+
+---
+
+## Step 6: Reviewer weighting (later, but powerful)
+
+Weight reviews by:
+
+- consistency
+- similarity to user preferences
+- past agreement
+
+This gives you:
+
+> “people like you liked this”
+
+---
+
+# 3. Example end-to-end
+
+### Raw reviews:
+
+| User | Food | Service |
+| ---- | ---- | ------- |
+| A    | 9    | 4       |
+| B    | 8    | 5       |
+| C    | 10   | 3       |
+
+---
+
+### Derived:
+
+- food → high positive ratio (~100%)
+- service → low (~33%)
+
+---
+
+### User preferences:
+
+```json
+{
+  "food": 0.8,
+  "service": 0.2
+}
+```
+
+→ ranks high
+
+Another user:
+
+```json
+{
+  "food": 0.3,
+  "service": 0.7
+}
+```
+
+→ ranks low
+
+👉 Same data, different truth
+That’s your killer feature.
+
+---
+
+# 4. Critical design choices (don’t skip these)
+
+## A. No global score in protocol
+
+Let clients compute it.
+
+---
+
+## B. Embrace incomplete data
+
+Most reviews will have:
+
+- 1–3 aspects only
+
+That’s fine.
+
+---
+
+## C. Time decay (important)
+
+Recent reviews should matter more:
+
+```text
+weight = e^(-λ × age)
+```
+
+---
+
+## D. Anti-gaming baseline
+
+Even in nostr:
+
+- spam will happen
+
+Mitigation later:
+
+- require minimum interactions
+- reputation layers
+
+---
+
+# 5. What you’ve built (zooming out)
+
+This is not a review system.
+
+It’s:
+
+> A decentralized, multi-dimensional reputation graph for real-world places
+
+That’s much bigger.
+
+---
+
+# 6. Next step (if you want to go deeper)
+
+We can design:
+
+### A. Query layer
+
+- how clients fetch & merge nostr reviews efficiently
+
+### B. Anti-spam / trust model
+
+- web-of-trust
+- staking / reputation
+
+### C. OSM integration details
+
+- handling duplicates
+- POI identity conflicts
+
+---
+
+If I had to pick one next:
+👉 **trust/reputation system** — because without it, everything you built _will_ get gamed.

+# Canonical Aspect Vocabulary (v0.1)
+
+## A. Core universal aspects
+
+These should work for _any_ place:
+
+```json
+[
+  "quality", // core offering (food, repair, exhibits, etc.)
+  "value", // value for money/time
+  "experience", // comfort, usability, vibe
+  "accessibility" // ease of access, inclusivity
+]
+```
+
+### Why these work
+
+- **quality** → your “product” abstraction (critical)
+- **value** → universally meaningful signal
+- **experience** → captures everything “soft”
+- **accessibility** → often ignored but high utility
+
+👉 Resist adding more. Every extra “universal” weakens the concept.
+
+---
+
+## B. Common cross-domain aspects (recommended pool)
+
+Not universal, but widely reusable:
+
+```json
+[
+  "service", // human interaction
+  "speed", // waiting time / turnaround
+  "cleanliness",
+  "safety",
+  "reliability",
+  "atmosphere"
+]
+```
+
+These apply to:
+
+- restaurants, garages, clinics, parks, etc.
+
+---
+
+## C. Domain-specific examples (NOT standardized)
+
+Let clients define freely:
+
+```json
+{
+  "restaurant": ["food", "drinks"],
+  "bar": ["drinks", "music"],
+  "garage": ["work_quality", "honesty"],
+  "park": ["greenery", "amenities"],
+  "museum": ["exhibits", "crowding"]
+}
+```
+
+---
+
+## D. Key rule (this prevents chaos)
+
+👉 **Aspect keys MUST be lowercase snake_case**
+
+👉 **Meaning is defined socially, not technically**
+
+To reduce fragmentation:
+
+- publish a **public registry (GitHub repo)**
+- clients can:
+  - suggest additions
+  - map synonyms
+
+---
+
+## E. Optional normalization hint (important later)
+
+Allow this:
+
+```json
+"aspect_aliases": {
+  "food": "quality",
+  "work_quality": "quality"
+}
+```
+
+Not required, but useful for aggregation engines.
+
+---
+
+## Notes
+
+Map familiarity in UI to:
+
+- high: “I know this place well”
+- medium: “Been a few times”
+- low: “First visit”
