+------------------------------------+          +---------------------------+          +-------------------------------+

1. Request Manifest Creation: The Gempatcher 7 Core Processing Unit initiates the manifest creation process by instructing the MFDB Interaction Module. It supplies a CreateManifestOptions object containing the necessary data for the manifest.
2. Call createManifest(): The MFDB Interaction Module invokes the createManifest function provided by the MFDB Core library. The CreateManifestOptions received in the prior step are passed as arguments.
3. Return BEJSONDocument: The createManifest function executes, constructing a manifest document in the BEJSONDocument format, compliant with MFDB spec v1.3.1. This document is returned to the MFDB Interaction Module.
4. Receive BEJSONDocument: The MFDB Interaction Module forwards the generated BEJSONDocument to the Gempatcher 7 Core Processing Unit for subsequent actions or storage.

6. Inter-Component Workflows

Gempatcher 7's components interact through defined workflows to achieve system objectives. Two core workflows include:

6.1 Initial Gem Scan and Manifest Generation

1. The GIC initiates a scan to identify "gems" in the environment.
2. For each newly identified "gem," the GIC provides relevant metadata to the MMC.
3. The MMC uses this metadata to generate an initial BEJSONDocument via mfdb_core.createManifest, representing the gem's baseline state.
4. The generated manifest is persisted.

6.2 Patch Application and Manifest Update

1. An external process or user input identifies a patch to be applied to a specific "gem."
2. The PAC receives a request to apply a specific patch to a target "gem" identified by the GIC.
3. The PAC performs the necessary operations to apply the patch to the physical "gem."
4. Upon completion of the patch operation, the PAC requests the MMC to update the target "gem"'s manifest. This update process involves reading the current manifest, incorporating changes reflecting the applied patch, and re-persisting the BEJSONDocument.

7. Technical Requirements for Architecture

The architectural components and their interactions are governed by the following technical requirements:

• The system shall be developed primarily in TypeScript.
• All manifest generation and manipulation shall adhere to the MFDB spec v1.3.1, leveraging mfdb_core.ts.
• Data exchange for manifests shall be exclusively in the BEJSON format.
• The system shall be designed for modularity, allowing independent development and testing of the GIC, MMC, and PAC.

4. Functional Requirements

Key Data Structures and Interfaces

This section describes the primary data structures and programming interfaces utilized by Gempatcher 7 for its operations, particularly in relation to manifest generation and management within the BEJSON environment.

1. Data Structures

Gempatcher 7 relies on specific BEJSON-compliant data structures for representing configuration and manifest content.

1.1 BEJSONDocument

• Description: The BEJSONDocument is a structured document that represents a manifest. It adheres to the Boehnen Elton JSON (BEJSON) format and the Multifile Database (MFDB) specification version 1.3.1. This structure serves as the standardized output for manifest generation operations within Gempatcher 7.

• Source: This structure is produced by the createManifest function within the mfdb_core.ts library.

• Format: A BEJSONDocument is a BEJSON object containing mandatory top-level keys such as Format, Format_Version, Format_Creator, Records_Type, Fields, and Values. For MFDB manifests, the Format_Version is "104a" and Records_Type is ["mfdb"]. It may also include custom headers as defined by BEJSON 104a and MFDB 1.3.1 for file-level metadata.

  Example (104a.mfdb.bejson snippet from MFDB specification):

  {
    "Format": "BEJSON",
    "Format_Version": "104a",
    "Format_Creator": "Elton Boehnen",
    "MFDB_Version": "1.31",
    "DB_Name": "StoreFront",
    // ... other metadata headers ...
    "Records_Type": ["mfdb"],
    "Fields": [
      {"name": "entity_name", "type": "string"},
      {"name": "file_path",   "type": "string"},
      // ... other fields ...
    ],
    "Values": [
      ["User",    "data/user.bejson"],
      ["Order",   "data/order.bejson"]
      // ... more records ...
    ]
  }
  

1.2 CreateManifestOptions

• Description: The CreateManifestOptions is an input data structure. It encapsulates the configuration parameters and data required by the createManifest function to define and construct a BEJSON manifest document. The precise schema for this structure is defined internally within mfdb_core.ts.
• Purpose: This structure allows Gempatcher 7 to specify details such as database name, description, schema version, and information about the entities to be registered in the manifest, as required by the MFDB specification.

2. Interfaces

Gempatcher 7 primarily interacts with external libraries through defined function interfaces.

2.1 createManifest Function

• Description: This function is a core interface provided by the mfdb_core.ts library. Its purpose is to generate a BEJSONDocument that functions as an MFDB manifest. This function implements the logic for creating manifests compliant with the MFDB specification version 1.3.1.
• Signature:

  export function createManifest(opts: CreateManifestOptions): BEJSONDocument;
  

• Parameters:
  • opts: CreateManifestOptions: An object containing the necessary options and data points for building the manifest.
• Return Value:
  • BEJSONDocument: A completed BEJSON manifest document formatted according to BEJSON 104a and MFDB spec v1.3.1.
• Usage in Gempatcher 7: The Manifest Management Component (MMC) and the MFDB Interaction Module within Gempatcher 7 utilize this function to generate initial manifests for discovered "gems" and to create deployment manifests for Gempatcher 7 itself.
