Repository Packaging and Encoding Formats

### Open Source Models (Llama, etc.)
- Square bracket delimiters: `[CODE]`, `[FILE]`
- Simple text markers with clear boundaries
- Minimal metadata overhead

## Collection Formats

### Archives
- tar (Unix tape archive)
- zip (ZIP archive format)
- rar (Roshal Archive)
- 7z (7-Zip format)
- ar (Unix archiver)
- cpio (Copy in/out format)
- shar (Shell archive)
- xar (eXtensible ARchive format)

### Version Control
- git bundle
- git patch format
- unified diff
- mercurial bundle
- svn dump format

### File System
- ISO 9660 (CD-ROM format)
- UDF (Universal Disk Format)
- SquashFS (compressed read-only file system)
- cramfs (Compressed ROM file system)

## Encoding Formats

### Text-Based
- Base64
- UUencode
- XXencode
- yEnc
- Quoted-Printable
- Percent encoding (URL encoding)

### Binary-to-Text
- Intel HEX
- Motorola S-record
- BinHex
- ASCII85

### Network/Transfer

- MessagePack
- Protocol Buffers
- Avro
- Thrift

## Structured Data Formats

### Human-Readable
- JSON
- YAML
- TOML
- INI
- XML
- Property lists (plist)
- CSV
- TSV

### Binary
- BSON (Binary JSON)
- CBOR (Concise Binary Object Representation)
- FlatBuffers

- ASN.1 (Abstract Syntax Notation One)

## Documentation Formats

### Markup
- Markdown
- AsciiDoc

- Textile
- Pod (Perl's Plain Old Documentation)

### Literate Programming

## Special Purpose

### Software Distribution

- MSI (Microsoft Installer)
- AppImage
- Snap
- Flatpak

### Container/Image
- Docker image format
- OCI (Open Container Initiative) format
- VM disk images (VMDK, VHD, QCOW2)
- Filesystem images (ext4, xfs, etc.)

## Performance Considerations

### Compression Ratio vs. Processing Speed
- High compression (7z, xz)
- Balanced (zip, gzip)
- Fast (lz4, zstd)
- No compression (tar)

### Random Access Capabilities
- Full (zip, 7z)
- Limited (tar)
- None (compressed streams)
