PhoenixmlDb.Core

Core types, interfaces, and XDM (XQuery Data Model) implementation for PhoenixmlDb — a modern embedded XML/JSON document database for .NET.

What's in this package

  • Database interfaces — IDocumentDatabase, IContainer, IDocument for storing and retrieving XML/JSON documents
  • XDM node types — XdmElement, XdmAttribute, XdmDocument, etc. — the W3C XQuery Data Model
  • Transaction model — IReadTransaction, IWriteTransaction with MVCC snapshot isolation
  • Index configuration — path, value, full-text, and metadata indexes for fast queries
  • XML parser and serializer — parse XML into XDM trees and serialize back
  • Atomic value types — dates, times, durations, and other XSD types with correct semantics

When to use this package

Directly: If you're building a storage provider, query engine integration, or tooling that works with XDM types.

Indirectly: This package is a dependency of PhoenixmlDb.XQuery, PhoenixmlDb.Xslt, and the CLI tools. You typically don't reference it alone unless you need the core types without query/transform capabilities.

Quick example

using PhoenixmlDb.Core;
using PhoenixmlDb.Xdm.Parsing;

// Parse XML into an XDM tree
var parser = new XmlDocumentParser();
var result = parser.Parse("<order><item>Widget</item></order>");
var doc = result.Document;

// Navigate the tree
var root = doc.Children[0]; // <order> element
Console.WriteLine(root.StringValue); // "Widget"
Package Description
PhoenixmlDb.XQuery XQuery 4.0 query engine
PhoenixmlDb.Xslt XSLT 4.0 transformation engine
PhoenixmlDb.XQuery.Cli xquery command-line tool
PhoenixmlDb.Xslt.Cli xslt command-line tool

**Major because it breaks builds, not only behaviour.** Part of the coordinated
namespace-consolidation train: `PhoenixmlDb.Core`, `PhoenixmlDb.XQuery` and `PhoenixmlDb.Xslt`
all move to 2.0.0 together.

> **This follows 1.7.0 directly.** Core was not part of the 1.8.0 train — it was unchanged, so
> nothing was published for it — and there is no Core 1.8.0 or 1.9.0 to look for.

### Breaking

- **`NamespaceId.PhoenixmlDb` (id 9, `https://schemas.phoenixml.dev/2026/db`) is retired.** The
 constant remains, marked `[Obsolete]`, and the registry no longer carries a row for it.

 **If you build with `TreatWarningsAsErrors` and name that constant, this release fails your
 build.** If you read id 9 out of `NamespaceRegistry` you now get nothing back. Both are
 deliberate: the namespace held only `dbxml:metadata`, which has moved.

- **Extension functions now live in `NamespaceId.PhoenixmlFunctions` (id 13),**
 `https://schemas.phoenixml.dev/2026/functions`, conventional prefix `phx`. All six extension
 functions move there — see `PhoenixmlDb.XQuery` 2.0.0.

- **`dbxml` now means only `https://schemas.phoenixml.dev/2026/meta`.** It is no longer
 overloaded between metadata and extension functions.

### Fixed

- **A no-namespace element opened in the ambient default namespace** rather than the empty one.
 An element written with no prefix, inside a scope carrying a default namespace, took that
 namespace instead of none.
