GENERICEQUATIONDESC

GENERICEQUATIONDESC defines a generic equation identifier with a description. The formulation of the generic equation is detailed in GENERICEQUATIONRHS.

GENERICEQUATIONDESC data is public to all participants.

Source

GENERICEQUATIONDESC updates when new a generic equation is created for the first time.

Volume

Approximately 100 records per year

Note

GENERICEQUATIONRHS and GENERICEQUATIONDESC allow commonly used constraint right hand side formulations to be defined as a generic equation. Once defined, the generic equation can be referenced from any Generic constraint RHS formulation defined in GENERICCONSTRAINTRHS.

Code Examples

Polars

Casting is enums, categoricals etc is not essential, but may speed up parsing. Swapping int for pl.UInt16, pl.Int32 would also speed up parsing. However some of the datatypes are inferred, so they may be wrong.

This code deduplicates for you. Deduplication is normally only required across multiple months.

This code assumes that all columns are present, which may not be true for older files.

Availability

Visibility: Public

This table is in the public monthly MMSDM archive.

I have collated the list of all those files into one place, in this CSV metadata file. (Columns year, month, url, compressed_size in bytes).

The earliest available data is month 1 of 2015. The most recent available data is month 9 of 2026.

Warning

There are some months with no files.

Data Size

Each year of data is approximately 28 KB when zipped, 276 KB as unzipped CSV.

Deduplication and PDR Loader Configuration

The primary keys are:

EQUATIONID

The transaction type is "INSERT-UPDATE", which means that you will likely see duplicate data with different values.

You should deduplicate by sorting based on LASTCHANGED, within each group of primary keys.

PDR Loader configuration is:

Report Name	Report Subtype	Version
GEQDESC	NULL	1
GEQDESC	NULL	2

This means that the CSV files start with metadata columns:

I,GEQDESC,NULL,1,...
D,GEQDESC,NULL,1,...

or

I,GEQDESC,NULL,2,...
D,GEQDESC,NULL,2,...

ROW_FILTER_TYPE is LASTCHANGED

Indexes
