OVPack

The OVPack API imports, exports, backs up, and restores OpenViking data.

API Reference

export_ovpack

Export a resource tree as a .ovpack file.

1. API Implementation Overview

Packages all resources under the specified URI into a .ovpack file for backup or migration. Available to ROOT, ADMIN, and USER roles; normal URI access controls still apply.

Processing Flow:

1. Verify user permissions
2. Traverse resources under the specified URI
3. Write content files and the OVPack manifest
4. Package into zip format (.ovpack)
5. Return as file stream

Format Notes:

• The exported ZIP stores user content unchanged under <root>/files/ and internal metadata under <root>/_ovpack/.
• The manifest is stored at <root>/_ovpack/manifest.json.
• entries[].path is relative to the exported root; "" means the root directory itself.
• File entries include size and sha256; content_sha256 covers the sorted file list of path, size, and sha256.
• _ovpack/index_records.jsonl stores portable index scalar fields. With include_vectors=true, _ovpack/dense.f32 stores a pure-dense float32 vector snapshot plus embedding metadata; vector indexes whose VectorIndex.IndexType is hybrid do not support vector snapshot export.
• Runtime fields such as id, uri, account_id, created_at, updated_at, and active_count are regenerated in the target environment and are not restored from the package.
• OVPack does not add package-size, file-count, or directory-depth limits; the practical limit comes from ZIP, the storage backend, and the runtime environment.

Code Entry Points:

• openviking/server/routers/pack.py:export_ovpack - HTTP router
• openviking/service/pack_service.py - Core service implementation
• crates/ov_cli/src/handlers.rs:handle_export - CLI handler

2. Interface and Parameter Description

Parameters

Permission Requirements: ROOT, ADMIN, or USER

3. Usage Examples

HTTP API

POST /api/v1/pack/export
Content-Type: application/json

curl -X POST http://localhost:1933/api/v1/pack/export \
  -H "Content-Type: application/json" \
  -H "X-API-Key: your-admin-key" \
  -d '{
    "uri": "viking://resources/my-project/",
    "include_vectors": false
  }' \
  --output my-project.ovpack

Python SDK

import openviking as ov

client = ov.SyncHTTPClient(url="http://localhost:1933", api_key="your-admin-key")
client.initialize()

# Export to local file (HTTP SDK automatically handles download)
# Note: Export functionality is primarily used via CLI

TypeScript SDK

const outputPath = await client.exportOVPack(
  "viking://resources/docs/",
  "./exports/docs.ovpack",
  true,
);
console.log(outputPath);

Go SDK

outPath, err := client.ExportOVPack(
    ctx,
    "viking://resources/my-project/",
    "./exports/my-project.ovpack",
    &openviking.PackOptions{IncludeVectors: false},
)
if err != nil {
    return err
}
fmt.Println(outPath)

CLI

# Export resource
ov export viking://resources/my-project/ ./exports/my-project.ovpack

# Export with a dense vector snapshot
ov export viking://resources/my-project/ ./exports/my-project.ovpack --include-vectors

Response Example

This endpoint directly returns a file stream (Content-Type: application/zip), does not return a JSON envelope.

import_ovpack

Import a .ovpack file.

1. API Implementation Overview

Imports a .ovpack file to a specified location for restoring or migrating data. Available to ROOT, ADMIN, and USER roles; normal URI access controls still apply.

Processing Flow:

1. Verify user permissions
2. Parse uploaded .ovpack file
3. Validate manifest metadata, paths, file and directory sets, file sizes, and checksums
4. Apply on_conflict
5. Import resources to target location and rebuild vectors

Code Entry Points:

• openviking/server/routers/pack.py:import_ovpack - HTTP router
• openviking/service/pack_service.py - Core service implementation
• crates/ov_cli/src/handlers.rs:handle_import - CLI handler

2. Interface and Parameter Description

Parameters

Permission Requirements: ROOT, ADMIN, or USER

Behavior Notes:

• The API no longer accepts vectorize or force.
• vector_mode=auto restores a compatible dense snapshot when present, otherwise recomputes vectors. recompute always ignores package vectors. require fails unless a compatible dense snapshot is present.
• Dense snapshot compatibility checks compare embedding provider, model, input mode, query/document parameters, and dimensions.
• Session files are part of the user namespace (viking://user/{user_id}/sessions/...) and do not trigger vectorization.
• on_conflict=fail returns a structured 409 CONFLICT when the target root already exists.
• on_conflict=overwrite replaces the existing target root. on_conflict=skip keeps the existing target root and returns it without writing package contents. skip is root-level, not file-level.
• Packages without a manifest are rejected by default because they cannot provide content integrity guarantees.
• Packages with manifest entries are rejected if content files or directories are missing, extra files or directories are present, file sizes differ, per-file sha256 differs, or content_sha256 is missing or differs.
• Packages whose manifest format_version is not the current supported version (3) are rejected.
• .abstract.md and .overview.md are restored as semantic sidecars. .relations.json and OVPack internals are excluded.
• Manifest context_type, when present in index scalar metadata, must match the final import path semantics.
• Top-level scope packages such as viking://resources/ must be imported to viking://.
• OVPack does not add import package-size, file-count, or directory-depth limits; the practical limit comes from ZIP, the storage backend, and the runtime environment.

3. Usage Examples

HTTP API

POST /api/v1/pack/import
Content-Type: application/json

# Step 1: Upload .ovpack file
TEMP_FILE_ID=$(
  curl -s -X POST http://localhost:1933/api/v1/resources/temp_upload \
    -H "X-API-Key: your-admin-key" \
    -F "file=@./exports/my-project.ovpack" \
  | jq -r '.result.temp_file_id'
)

# Step 2: Import
curl -X POST http://localhost:1933/api/v1/pack/import \
  -H "Content-Type: application/json" \
  -H "X-API-Key: your-admin-key" \
  -d "{
    \"temp_file_id\": \"$TEMP_FILE_ID\",
    \"parent\": \"viking://resources/imported/\",
    \"on_conflict\": \"overwrite\",
    \"vector_mode\": \"auto\"
  }"

Python SDK

import openviking as ov

client = ov.SyncHTTPClient(url="http://localhost:1933", api_key="your-admin-key")
client.initialize()

# Import .ovpack file (HTTP SDK automatically handles upload)
# Note: Import functionality is primarily used via CLI

TypeScript SDK

const uri = await client.importOVPack(
  "./exports/docs.ovpack",
  "viking://resources/",
  {
    onConflict: "overwrite",
    vectorMode: "auto",
  },
);
console.log(uri);

Go SDK

uri, err := client.ImportOVPack(
    ctx,
    "./exports/my-project.ovpack",
    "viking://resources/imported/",
    &openviking.ImportPackOptions{
        OnConflict: "overwrite",
        VectorMode: "auto",
    },
)
if err != nil {
    return err
}
fmt.Println(uri)

CLI

# Import .ovpack file
ov import ./exports/my-project.ovpack viking://resources/imported/

# Explicit conflict policy
ov import ./exports/my-project.ovpack viking://resources/imported/ --on-conflict overwrite

# Require restoring a compatible dense vector snapshot
ov import ./exports/my-project.ovpack viking://resources/imported/ --vector-mode require

Response Example

{
  "status": "ok",
  "result": {
    "uri": "viking://resources/imported/my-project/"
  },
  "telemetry": {
    "operation_id": "550e8400-e29b-41d4-a716-446655440000"
  }
}

Conflict Error Example

{
  "status": "error",
  "error": {
    "code": "CONFLICT",
    "message": "Resource already exists at viking://resources/imported/my-project. Use on_conflict='overwrite' to replace it.",
    "details": {
      "resource": "viking://resources/imported/my-project"
    }
  }
}

backup_ovpack

Back up public scope roots as a restore-only .ovpack file. The backup includes resources and user; sessions are included through the user namespace under user/{user_id}/sessions. It excludes internal runtime data such as temp and queue. Set include_vectors=true to include compatible pure-dense vector snapshots; hybrid index types reject vector snapshot export.

POST /api/v1/pack/backup

curl -X POST http://localhost:1933/api/v1/pack/backup \
  -H "Content-Type: application/json" \
  -H "X-API-Key: your-admin-key" \
  -d '{"include_vectors":false}' \
  --output openviking-backup.ovpack

Go SDK:

outPath, err := client.BackupOVPack(
    ctx,
    "./backups/openviking.ovpack",
    &openviking.PackOptions{IncludeVectors: true},
)
if err != nil {
    return err
}
fmt.Println(outPath)

CLI:

ov backup ./backups/openviking.ovpack
ov backup ./backups/openviking.ovpack --include-vectors

Response

On HTTP success, the endpoint returns an application/zip byte stream instead of the standard JSON envelope:

HTTP/1.1 200 OK
Content-Type: application/zip
Content-Disposition: attachment; filename="openviking-backup.ovpack"

<ovpack binary body>

The Go SDK and CLI write the stream to the requested path and return or print that local path.

restore_ovpack

Restore a backup package created by backup_ovpack to the original public scope roots. Regular import rejects backup packages. Vector handling follows vector_mode; session files under the user namespace are restored without vectorization.

POST /api/v1/pack/restore
Content-Type: application/json

TEMP_FILE_ID=$(
  curl -s -X POST http://localhost:1933/api/v1/resources/temp_upload \
    -H "X-API-Key: your-admin-key" \
    -F "file=@./backups/openviking.ovpack" \
  | jq -r '.result.temp_file_id'
)

curl -X POST http://localhost:1933/api/v1/pack/restore \
  -H "Content-Type: application/json" \
  -H "X-API-Key: your-admin-key" \
  -d "{\"temp_file_id\":\"$TEMP_FILE_ID\",\"on_conflict\":\"overwrite\",\"vector_mode\":\"auto\"}"

Go SDK:

uri, err := client.RestoreOVPack(
    ctx,
    "./backups/openviking.ovpack",
    &openviking.ImportPackOptions{
        OnConflict: "overwrite",
        VectorMode: "require",
    },
)
if err != nil {
    return err
}
fmt.Println(uri)

CLI:

ov restore ./backups/openviking.ovpack --on-conflict overwrite
ov restore ./backups/openviking.ovpack --on-conflict overwrite --vector-mode require

Response

{
  "status": "ok",
  "result": {
    "uri": "viking://"
  }
}

uri is the public scope root restored from the backup.
