Overview

This release is a significantly enhances support for XML Schema, an introduces generated mapping for ISO20022 messages.

ISO20022 includes a large family of 761 XSD schema files comprising 39954 separate type definitions (many of which are duplicated in each schema file, but some specific domain variations). As a proof-of-principle the message schema has been mapped as-is with payments messages augmented to show how a Graph and Cube functionality can be added with minimal changes to store messages in hiperspace. Messages stored in hiperspace are naturally compressed from the XML or JSON source using protobuf encoding that replaces type names with the equivalent #id and native types instead of text encoding.

Hilangc changes

Import of XSD schema has been added to the command-line tool

Option	┃	Notes
--xsd	┃	Import the XML schema file (.xsd) to an equivalent hilang model
--xn	┃	Set the XML schema tag for all imported elements
--xe	┃	Import references to a list of names as entities
--xs	┃	Import references to a list of names as segments
--xa	┃	Import references to a list of names as aspects
--xt	┃	Import references to a list of names as abstract types - the default is values

Hilang changes

The directive %reference (domain.schema.dll); imports elements from pre-compiled domain schema all.hilang uses the reference import to build a consolidated ISO20022 schema including element definitions from each domain specific models {acmt, admi, auth, caaa, caad, caam, cafc, cafm, cafr, cain, camt, canm, casp, casr, catm, catp, colr, fxtr, head, pacs, pain, reda, remt, secl, seev, semt, sese, setr, trck, tsin, tsmt, tsrv}

The directive %annotations; has been added to simplify maintenance of XSD mapping. The code

@XmlNameSpace ("urn:iso:std:iso:20022:tech:xsd:pain.001.001.12"), ValidationCheck
entity ISO20022.Pain001001.CustomerCreditTransferInitiationV12 #35044
(
    @XmlElement GrpHdr             : ISO20022.Pain001001.GroupHeader114 #1,
)
{
    @XmlElement SplmtryData        : List<ISO20022.Pain001001.SupplementaryData1> #2,
};

could be modeled as

@XmlNameSpace ("urn:iso:std:iso:20022:tech:xsd:pain.001.001.12"), ValidationCheck
entity ISO20022.Pain001001.CustomerCreditTransferInitiationV12 #35044
{
    @Key, XmlElement GrpHdr             : ISO20022.Pain001001.GroupHeader114 #1,
    @XmlElement SplmtryData             : List<ISO20022.Pain001001.SupplementaryData1> #2,
};

to transform the the GrpHdr element of ISO20022.Pain001001.CustomerCreditTransferInitiationV12 from a value to a key without reordering the memvbers of the element.
This is intended to simplify the tracking of a golden-source of model using code change-control tools

Hiperspace changes

Various Hiperspace structures have been changed from struct to class to avoid stack-space issues with huge models. netstandard2.0 has been added as a target for Hiperspace assembly to enable meta-data definitions to be read by Hilang during compilation (or generation using hilangc)

Interface functions that were marked as Obsolete in earlier releases have been removed.

Additional Transactional versions of the Bind, Get and Find functions have been added, initially using the old functions. These functions take a MVCC Transaction reference has an additional parameter and a DurableType to allow the functions to be used for:

Type	┃	Notes
Elements	┃	Entities, Segments, Aspects
Versioned	┃	Versioned Entities, Segments, Aspects
MetaModel	┃	dictionary that ensures that Hiperspaces cannot be used by incompatible clients
VectorSpace	┃	VectorSpace token lists for geospatial and nearest neighbor search
Sequences	┃	Sequence numbers
Transaction	┃	{start, end, reference} elements for MVCC
MetaMap	┃	protobuf transformation structure for Meta-Model compliant serialisation of elements
Fingerprint	┃	To avoid re-generation of meta-map when Hiperspace has been reopened by a pre-validated client

Hiperspace Find will search for hiperspace using the key or index values. The new function extends the search parameters to include a collection of values that are not part of a key/index to reduce the number of elements returned from hiperspace to pre-filter elements close to source.
