What format is this export of election data in?

I have a series of files I've downloaded from the [Texas Ethics Commission](https://www.ethics.state.tx.us/dfs/search_CF.htm) (a misnamed . You can see an example of their [layout in the ReadMe.txt](https://www.ethics.state.tx.us/tedd/CFS-ReadMe.txt) . I've made an [tag:ETL] library which processes the [ReadMe.txt](https://www.ethics.state.tx.us/tedd/CFS-ReadMe.txt) to generate the [SQL DDL](https://en.wikipedia.org/wiki/Data_definition_language) to create this schema, and load it from the CSVs. The thing is, I *think* this is a standardized format. I imagine it's backed by something like a PICK (which is a BASIC database) or something COBOL-esque -- having worked with them before, and that this is something like a [MARC](https://en.wikipedia.org/wiki/MARC_standards) , or ANSI, or ISO standard. I'd like to potentially abstract out my ETL script to benefit others who use this format. Some identifying features of the format are that it supports * Arrays and internal one-to-many relations on the record * at least types BigDecimal, Long, Date, String * the export is labeled "Flat File Architecture Record Listing" Arrays ===== For example here you see this, Array 4050 loanGuarantorLoanPersent[5/ROW_MAJOR] CsvPublicExportLoanGuarantorLoanPersent 810 Guarantors for the loan (maximum 5) 46 guarantorPersentTypeCd String 30 Type of guarantor name data - INDIVIDUAL or ENTITY 47 guarantorNameOrganization String 100 For ENTITY, the guarantor organization name 48 guarantorNameLast String 100 For INDIVIDUAL, the guarantor last name That defines a structure called a loanGuarantorLoanPersent and essentially declares that there are five of them. So the export CSV will have something like guarantorPersentTypeCd1,guarantorNameOrganization1,guarantorNameLast1,guarantorPersentTypeCd2,guarantorNameOrganization2,guarantorNameLast2,guarantorPersentTypeCd3,guarantorNameOrganization3,guarantorNameLast3...
