Editing PDMS/Requirements (section)

== 2. Overall Description ==

<span id="product-perspective"></span>
=== 2.1 Product Perspective ===

The PDMS module is a component of the larger Logos Microkernel ecosystem. It depends on:

===== Logos Anonymous DHT =====
* Provides decentralized routing infrastructure
* Enables anonymous data storage and retrieval
* Supports secure peer discovery

The PDMS module indirectly interfaces with:

===== Codex Module =====
* Provides semantic content discovery
* Indexes stored content metadata
* Enables content queries using SPARQL-Star

===== Package Manager Module =====
* Stores package version history as RDF-Star data
* Tracks package dependencies and metadata
* Manages package distribution and updates

===== Blockchain Systems =====
* Offers unified query interface via RML adapters
* Translates blockchain state to RDF model
* Supports cross-chain queries

=== 2.2 Product Functions ===

===== RDF-Star Data Management =====
* The system MUST:
** Store and manage RDF-Star triples
** Support basic named graphs
** Provide distributed indexing

* The system SHOULD:
** Support nested assertions
** Enable advanced graph operations
** Optimize replication strategies

===== SPARQL-Star Query Processing =====
* The system MUST:
** Execute distributed SPARQL-Star queries
** Implement basic query optimization
** Support incremental results

* The system SHOULD:
** Provide advanced optimization
** Enable parallel processing
** Support complex aggregations

=== 2.3 User Classes and Characteristics ===

===== Application Developers =====
* Primary users of the PDMS API
* Need documentation and examples
* Require stable interfaces
* Technical expertise with RDF/SPARQL

===== Other Logos Modules =====
* Automated system interactions
* High performance requirements
* Internal API usage
