Resources and LinksOfficial sources, GitHub repository, community, and training offerings

This appendix collects the external resources that a FundsXML practitioner is most likely to need. It is organised by category rather than alphabetically, so that a reader looking for a specific kind of resource can find the right section quickly. URLs are current as of early 2026; if a link has moved by the time you read this, the organisation name and resource description should give you enough context to find the new location.

E.1 The FundsXML Association

The FundsXML association is the non-profit body that stewards the standard. Its website is the authoritative source for governance information, membership details, working-group schedules, and announcements.

• FundsXML association website — https://www.fundsxml.org — The official home of the standard. Contains the current schema files, the release changelog, the membership list, the board composition, and the working-group calendar. The website also hosts the association's contact form for enquiries about membership, schema questions, and working-group participation.
• FundsXML GitHub repository — https://github.com/fundsxml — The public repository where the schema files, sample documents, and related tooling are maintained. The issue tracker on the repository is the primary channel for reporting schema bugs, requesting clarifications, and proposing new features. Readers who want to contribute should start here. → Chapter 14 for the contribution process.
• FundsXML schema releases — https://github.com/fundsxml/schema/releases — Tagged releases of the FundsXML schema, each with the XSD file, changelog, and release notes. The URL pattern https://github.com/fundsxml/schema/releases/download/{version}/FundsXML.xsd gives direct access to any version (see §4.7.2).
• FundsXML implementation guide — https://www.fundsxml.org/implementation-guide/ — Practical guidance for getting started with the standard, including the root-element declaration and schema referencing.
• FundsXML downloads — https://www.fundsxml.org/downloads/ — Schema files, sample documents, and supplementary materials available for direct download.
• FundsXML community — https://www.fundsxml.org/community/ — Community resources, discussion channels, and announcements.

E.2 Schema and Specification Files

• FundsXML4.xsd — Available from https://github.com/fundsxml/schema/releases and from the association website. The file is approximately 1.7 MB and defines the complete structure of a valid FundsXML 4.x document.
• xmldsig-core-schema.xsd — The W3C XML Digital Signature schema, imported by FundsXML4.xsd for the optional ds:Signature element. Available from https://www.w3.org/TR/xmldsig-core/ and typically bundled with the FundsXML schema distribution.
• FundsXML Online Schema Documentation — https://fundsxml.github.io — An interactive, browser-based reference for the FundsXML 4.x schema. Every element is navigable by XPath: appending ?xpath=/FundsXML4/ControlData to the URL, for example, opens the documentation for the ControlData node directly. The documentation shows each element's type, cardinality, child elements, and annotations. This is the quickest way to look up a specific node without opening the XSD in an editor. Throughout this book, element names in the running text link directly to the corresponding page in this documentation. Table E.1 below lists the most important entry points.
• FundsXML Release Changelog — Published alongside each release on https://github.com/fundsxml/schema/releases, the changelog enumerates every field added, removed, or changed. Essential reading when upgrading a pipeline from one version to the next.
• FundsXML Documentation — https://www.fundsxml.org/downloads/ — The association publishes supplementary documentation for the schema, including element-by-element descriptions, usage guidelines, and worked examples.

E.3 FinDatEx Templates

The five FinDatEx regulatory templates embedded in FundsXML are published and maintained by FinDatEx, not by the FundsXML association. Each template has its own specification document, field-by-field definition, and version history.

• FinDatEx website — https://findatex.eu — The official home of the European Working Group on Investment Data Exchange. Contains the current versions of all templates, the consultation documents for upcoming versions, and the working-group meeting calendar.
• EMT (European MiFID Template) — Current version: v4.3. The specification document defines approximately 150 fields covering target market, costs, risk classification, and distribution strategy. Published as an Excel workbook with field definitions and as a PDF specification.
• EPT (European PRIIPs Template) — Current version: v2.1. Defines the inputs needed for PRIIPs KID generation: performance scenarios, cost structures, risk indicators, and recommended holding periods.
• EET (European ESG Template) — Current version: v1.1.3. Carries SFDR-mandated sustainability disclosures: PAI indicators, Taxonomy alignment percentages, sustainable investment share, and exclusions policy.
• EFT (European Feedback Template) — Current version: v1.0. Facilitates the exchange of feeder-fund-specific information between feeder and master funds.
• TPT (Tripartite Template) — Current version: v7.0. Used for institutional Solvency II reporting of portfolio composition between asset managers, insurance clients, and their regulators.

E.4 Tooling

E.4.1 FreeXmlToolkit

FreeXmlToolkit is the open-source desktop application covered in Chapter 11. It provides an integrated environment for editing, validating, transforming, and signing FundsXML files.

• FreeXmlToolkit GitHub repository — https://github.com/karlkauc/FreeXmlToolkit — Source code, binary releases, issue tracker, and contribution guide. The application is written in Java and JavaFX and runs on Windows, macOS, and Linux.

E.4.2 Validation Tools

• xmllint — https://gitlab.gnome.org/GNOME/libxml2 — The command-line XML validator from the libxml2 project. Available on virtually all Linux and macOS systems and installable on Windows via MSYS2 or WSL. Used throughout this book for schema validation. Invocation: xmllint --schema FundsXML4.xsd file.xml --noout.
• Saxon — https://www.saxonica.com — The reference XSLT 2.0 / 3.0 and XPath 2.0 / 3.1 processor, available in open-source (Saxon-HE) and commercial (Saxon-PE, Saxon-EE) editions. Useful for Schematron validation (which requires an XSLT processor) and for complex XPath queries.
• lxml (Python) — https://lxml.de — The Python binding for libxml2 and libxslt. Provides schema validation, XPath queries, XSLT transformation, and ISO Schematron support through the lxml.isoschematron module. Used in the Chapter 10 and Chapter 12 code examples.

E.4.3 Programming Libraries

The four languages covered in Chapter 12 each have standard XML libraries suitable for FundsXML work:

• Java: JAXP — The Java API for XML Processing, included in the standard JDK. Provides DOM, SAX, StAX parsing, XPath evaluation, schema validation, and XSLT transformation.
• Python: lxml — See above. The lxml.etree module is the recommended library for FundsXML work in Python.
• C#: System.Xml.Linq (LINQ to XML) — The .NET standard library for XML processing. Provides XDocument/XElement for document construction and query, plus XmlSchemaSet for validation.
• JavaScript/Node.js: fast-xml-parser — https://www.npmjs.com/package/fast-xml-parser — A high-performance XML parser for Node.js. Used in the Chapter 12 example. Alternative: xml2js for a more DOM-like API.

E.8 Companion Files from This Book

The following files accompany this book and are available for download from the book's repository. They are designed to be used together: the sample FundsXML file provides the input, and the XSLT stylesheets and programming-language scripts process it. Readers are encouraged to download all files, run the examples, and adapt them to their own FundsXML data.

E.8.1 Sample Data

E.8.2 XSLT Stylesheets

All stylesheets are XSLT 1.0 and can be run with xsltproc (bundled with libxml2 on Linux and macOS), with Saxon, or with any XSLT-capable library (Python lxml, Java javax.xml.transform, .NET System.Xml.Xsl).

E.8.3 Programming-Language Examples

Each script reads or processes europa_growth_fund.xml. Run instructions and dependency notes are included as comments at the top of each file.

Python (requires lxml; install with pip install lxml)

Java (JDK 17+; external libraries noted per file)

C# (.NET 8+)

JavaScript / Node.js (requires fast-xml-parser; install with npm install fast-xml-parser)

E.9 FundsXML Online Schema Documentation — Quick Reference

The interactive schema documentation at https://fundsxml.github.io allows direct navigation to any element via an XPath parameter in the URL. The general pattern is:

https://fundsxml.github.io/index.html?xpath=/FundsXML4/…

Table E.1 lists the most frequently needed entry points. Each URL opens the documentation page for the corresponding node, showing its type definition, cardinality, child elements, and schema annotations.

Table E.1 — Key entry points into the FundsXML Online Schema Documentation

Readers are encouraged to bookmark the root URL and explore the schema tree interactively. The documentation is generated directly from the XSD and therefore always reflects the structure of the published schema version.
