The Concordance File

The concordance is an RDB to XML Crosswalk that maps all xpaths onto a specified set of variables. It is located in the irs990efile package.


The full data dictionary is available on GitHub.

Diagnostics

Missing or Extra XPATHS

Check for xpaths that were used in the tables but do not exist in the Concordance file.

c.table <- dplyr::filter( concordance, rdb_table == table.name ) 
xpath.concordance <- c.table$xpath
setdiff( all.xpaths, xpath.concordance )
## [1] ""                                                                                              
## [2] "/Return/ReturnData/IRS990ScheduleL/BusTrInvolveInterestedPrsnGrp/NameOfInterested"             
## [3] "/Return/ReturnData/IRS990ScheduleL/BusTrInvolveInterestedPrsnGrp/NameOfInterested/BusinessName"

Capture to update the Concordance file.

these <- setdiff( all.xpaths, xpath.concordance )
cat( these, sep="\n", file=paste0( folder.name, "/MISSING-XPATHS.txt" ) )

Failes URLs

Check the status of failed URLs.

if( length(fail.log) > 0 )
{ 
  sapply( fail.log, get_message ) %>% 
  table() %>% 
  pander() 
} else {
  print("ALL URLs ARE VALID")
}
## [1] "ALL URLs ARE VALID"








XML Table Structure

Create Network Edgelists

The create_edgelist() functions v1 and v2 are in R/utils.R.

V1 retains the root nodes Return and ReturnData.

V2 drops the root nodes and uses form versions “990” and “990EZ” as the root to visualize the sets of tables separately.

# KEEP ROOT NOTES Return & ReturnData
el <- create_edgelist_v1( all.xpaths )



Edgelist format:

V1 V2
Return ReturnData
ReturnData IRS990
IRS990 Form990PartVIISectionAGrp
Form990PartVIISectionAGrp PersonNm
Form990PartVIISectionAGrp TitleTxt
Form990PartVIISectionAGrp AverageHoursPerWeekRt

Form990PartVIISectionAGrp ReportableCompFromOrgAmt

Grouping Variables

Identify all unique groups used in xpaths.

if( is.null(table.headers) )
{ find_table_headers( table.name ) } else
table.headers
##  [1] "//BusTrInvolveInterestedPrsnGrp/NameOfInterested"

##  [9] "//Form990ScheduleLPartIV/DescriptionOfTransaction"         
## [10] "//Form990ScheduleLPartIV/SharingOfRevenues"

Groups can then be used to extract the 1:M RDB tables:

if( is.null(table.headers) )
{ table.headers <- find_table_headers( table.name ) }
demo.url <- "https://nccs-efile.s3.us-east-1.amazonaws.com/xml/201913079349300206_public.xml"
doc <- xml2::read_xml( demo.url )
xml2::xml_ns_strip( doc )
df.demo <- get_table_v2( doc, table.name, table.headers )
df.demo 
## NULL

Standardize Variable Names

Mapping of xml variable names to concordance variable names:

get_var_map( table.name=table.name )

A table with proper names:

v.map <- get_var_map( table.name=table.name )

if( ! is.null(df.demo) )
{re_name( df.demo, v.map ) %>% as.data.frame()}
