OSIRIS

Object Storage, Indexing & Retrieval Intelligent System

OSIRIS is a Rust-native object storage and retrieval layer built on top of HeroDB, providing structured storage with metadata, field indexing, and search capabilities.

Features

• Object Storage: Store structured objects with metadata (title, tags, MIME type, timestamps)
• Namespace Management: Organize objects into isolated namespaces
• Field Indexing: Fast filtering by tags and metadata fields
• Text Search: Simple keyword-based search across object content
• CLI Interface: Command-line tools for object management and search
• 9P Filesystem: Mount OSIRIS as a filesystem (future)

Quick Start

Prerequisites

Start HeroDB:

cd /path/to/herodb
cargo run --release -- --dir ./data --admin-secret mysecret --port 6379

Installation

cd /path/to/osiris
cargo build --release

Initialize

# Create configuration
mkdir -p ~/.config/osiris
cat > ~/.config/osiris/config.toml <<EOF
[herodb]
url = "redis://localhost:6379"

[namespaces.notes]
db_id = 1
EOF

# Initialize OSIRIS
./target/release/osiris init --herodb redis://localhost:6379

# Create a namespace
./target/release/osiris ns create notes

Usage

# Add objects
./target/release/osiris put notes/my-note.md ./my-note.md --tags topic=rust,project=osiris

# Get objects
./target/release/osiris get notes/my-note.md

# Search
./target/release/osiris find --ns notes --filter topic=rust
./target/release/osiris find "retrieval" --ns notes

# Delete objects
./target/release/osiris del notes/my-note.md

# Show statistics
./target/release/osiris stats --ns notes

Data Model

Objects are stored with metadata:

• ID: Unique identifier (UUID or user-assigned)
• Namespace: Logical grouping (e.g., "notes", "calendar")
• Title: Optional human-readable title
• MIME Type: Content type
• Tags: Key-value pairs for categorization
• Timestamps: Created and updated times
• Text Content: Optional plain text content

Keyspace Design

meta:<id>             → serialized OsirisObject
field:<field>:<val>   → Set of IDs (for equality filtering)
scan:index            → list of IDs for text scan

Example:

field:tag:project=osiris  → {note_1, note_2}
field:mime:text/markdown  → {note_1, note_3}

Future Enhancements

• Content-addressable deduplication
• Vector embeddings for semantic search
• Relation graphs
• Full-text search with Tantivy
• 9P filesystem interface
