XBRL Standardization Concepts Reference
This document describes the 95 standard concepts used by EdgarTools to normalize XBRL financial data across different companies. These concepts enable cross-company comparison by mapping the ~18,000 possible SEC GAAP taxonomy tags to a consistent set of standardized line items.
How Standardization Works
Labels are always preserved - the company's original presentation is shown exactly as filed.
Standardization adds a standard_concept column to DataFrames, mapping each line item to
one of 95 standard categories:
# Get a statement DataFrame
df = statement.to_dataframe()
# Labels show original company presentation
# standard_concept maps to standard categories for analysis
print(df[['label', 'standard_concept']].head())
# label standard_concept
# 0 Cash and cash items CashAndMarketableSecurities
# 1 Trade receivables, net TradeReceivables
# 2 Prepaid expenses OtherNonOperatingCurrentAssets
# Aggregate by standard concept for cross-company comparison
standardized = df.groupby('standard_concept')[['2024-09-30']].sum()

Concept Details
Balance Sheet Concepts
Current vs Non-Current Classification
The taxonomy distinguishes between current (due within 1 year) and non-current items:
- Current Assets:
CashAndMarketableSecurities,TradeReceivables,Inventories, etc. - Non-Current Assets:
PlantPropertyEquipmentNet,Goodwill,LongtermInvestments, etc. - Current Liabilities:
TradePayables,ShortTermDebt, etc. - Non-Current Liabilities:
LongTermDebt,DeferredTaxNonCurrentLiabilities, etc.
Operating vs Non-Operating Classification
Items are also classified by their relationship to core operations:
- Operating: Related to primary business activities (e.g.,
OtherOperatingCurrentAssets) - Non-Operating: Related to financing/investing activities (e.g.,
OtherNonOperatingCurrentAssets)
Income Statement Concepts
Revenue Recognition
All revenue-related XBRL tags (139 variations) map to the single Revenue concept.
This includes:
- RevenueFromContractWithCustomerExcludingAssessedTax
- Revenues
- SalesRevenueNet
- SalesRevenueGoodsNet
- And 135 more industry-specific variations
Cost of Revenue
Cost tags (142 variations) map to CostOfGoodsAndServicesSold:
- CostOfRevenue
- CostOfGoodsAndServicesSold
- CostOfGoodsSold
- CostOfServices
Operating Lease Accounting (ASC 842)
Following the ASC 842 lease accounting standard, the taxonomy includes:
- Right-of-Use Asset:
OperatingLeaseRightOfUseAsset - Current Liability:
OperatingLeaseCurrentDebtEquivalent - Non-Current Liability:
OperatingLeaseNonCurrentDebtEquivalent - Future Commitments: Years 1-5 and thereafter
Provisions and Reserves
The taxonomy distinguishes between:
- Ongoing Provisions:
OngoingOperatingProvisions(WarrantiesEtc)- recurring obligations - Definite-Lived Provisions:
DefiniteLivedOperatingProvisions(DecommissioningEtc)- asset retirement - Restructuring:
RestructuringProvisions- one-time reorganization costs
Ambiguous Tags
Some XBRL tags can map to multiple concepts depending on context. These are flagged as "ambiguous" and require context-aware resolution (Phase 4 of implementation).
Total Ambiguous Tags: 215 (9.2% of mapped tags)
Common Ambiguity Types
- Current/Non-Current Ambiguity (202 tags)
- Example:
AccountsPayableCurrentAndNoncurrent→TradePayablesOROtherOperatingNonCurrentLiabilities -
Resolution: Based on balance sheet section placement
-
Asset/Liability Ambiguity (12 tags)
- Example:
DeferredTaxAssetsLiabilitiesNet→DeferredTaxNoncurrentAssetsORDeferredTaxNonCurrentLiabilities -
Resolution: Based on sign (positive = asset, negative = liability)
-
Operating/Non-Operating Ambiguity
- Example:
OtherAssetsNoncurrent→OtherOperatingNonCurrentAssetsOROtherNonOperatingNonCurrentAssets - Resolution: Based on statement section context
Excluded Tags (DropThisItem)
276 XBRL tags are explicitly excluded from standardization because they: - Confuse financial analysis (EPS details, pro-forma metrics) - Are redundant with other tags - Don't map cleanly to standard concepts
Examples of excluded tags:
- AcceleratedShareRepurchasesFinalPricePaidPerShare
- BasicEarningsPerShareProForma
- BusinessAcquisitionProFormaEarningsPerShareBasic
- Various per-share calculation details
Deprecated Tags
410 XBRL tags are marked as deprecated by the SEC with the year of deprecation. The mapping still works for historical filings, but these tags should not appear in recent filings.
Example:
- Revenues (deprecated 2018) → Still maps to Revenue
- AccountsPayableRelatedPartiesCurrent (deprecated 2023) → Still maps to TradePayables
Python API (v5.9.0+)
EdgarTools provides several APIs for working with standardized concepts:
Module-Level Singletons (Recommended)
For best performance, use the module-level singletons which load mappings once per session:
from edgar.xbrl.standardization import (
get_default_mapper,
get_default_store,
StandardConcept,
StandardizationCache
)
# Get the singleton mapper - eliminates redundant file I/O
mapper = get_default_mapper()
# Map a company concept to standardized label
label = mapper.map_concept(
"us-gaap_AccountsPayableCurrent",
"Accounts Payable",
{"statement_type": "BalanceSheet"}
)
# Returns: "Accounts Payable"
StandardConcept Enum
Type-safe enum for all standardized concepts:
from edgar.xbrl.standardization import StandardConcept
# Access standard concept labels
StandardConcept.REVENUE.value # "Revenue"
StandardConcept.NET_INCOME.value # "Net Income"
StandardConcept.TOTAL_ASSETS.value # "Total Assets"
StandardConcept.ACCOUNTS_PAYABLE.value # "Accounts Payable"
# Look up a concept by its label
concept = StandardConcept.get_from_label("Revenue")
# Returns: StandardConcept.REVENUE
# Get all available standard values
all_values = StandardConcept.get_all_values()
# Returns: {'Revenue', 'Net Income', 'Total Assets', ...}
StandardizationCache (Per-XBRL Caching)
For high-performance workflows, use StandardizationCache which caches results per XBRL instance:
# The cache is automatically attached to XBRL instances
xbrl = filing.xbrl()
# Access via the standardization property
cache = xbrl.standardization
# Get cached label lookups
label = cache.get_standard_label(
"us-gaap_Revenue",
"Total Revenue",
{"statement_type": "IncomeStatement"}
)
# Standardize entire statement with caching.
# Note: pass the raw line-item list from get_statement(), NOT the dict
# returned by get_statement_by_type() (that dict's `data` key holds the list).
raw_data = xbrl.get_statement("IncomeStatement")
standardized = cache.standardize_statement_data(raw_data, "IncomeStatement")
# Check cache statistics
print(cache.cache_stats)
# {'label_cache_size': 42, 'statement_cache_size': 1, 'cached_statements': ['IncomeStatement']}
# Clear cache when needed
cache.clear_cache() # Clear all
cache.clear_cache("IncomeStatement") # Clear specific statement
Reverse Index API (Low-Level)
Direct O(1) lookup for XBRL tags:
from edgar.xbrl.standardization.reverse_index import (
get_standard_concept,
get_display_name,
lookup
)
# Simple lookup
concept = get_standard_concept("AccountsPayableCurrent")
# Returns: "TradePayables"
display = get_display_name("AccountsPayableCurrent")
# Returns: "Accounts Payable"
# Full result with metadata
result = lookup("AccountsPayableCurrentAndNoncurrent")
result.is_ambiguous # True
result.standard_concepts # ['TradePayables', 'OtherOperatingNonCurrentLiabilities']
result.display_names # ['Accounts Payable', 'Other Non-Current Liabilities']
result.comment # 'Curr/NonCurr ambiguity'
Checking Coverage
from edgar.xbrl.standardization.reverse_index import get_reverse_index
index = get_reverse_index()
print(index.stats)
# {'total_mappings': 2067, 'ambiguous_count': 215, 'deprecated_count': 410, 'excluded_count': 276}
Context-Aware Disambiguation
Starting in v5.9.0, EdgarTools uses context-aware disambiguation to resolve ambiguous tags.
How It Works
Ambiguous tags (e.g., AccountsPayableCurrentAndNoncurrent) can map to multiple concepts.
EdgarTools uses two complementary strategies to disambiguate:
1. Calculation Parent Derivation
When an item has a calculation_parent, EdgarTools infers its section:
# Item with calculation_parent="us-gaap:AssetsCurrent"
# → Inferred section: "Current Assets"
# → Resolves ambiguity toward current asset concepts
# Supported parent → section mappings:
# AssetsCurrent → "Current Assets"
# AssetsNoncurrent → "Non-Current Assets"
# LiabilitiesCurrent → "Current Liabilities"
# LiabilitiesNoncurrent → "Non-Current Liabilities"
# StockholdersEquity → "Equity"
2. Bottom-Up Section Scanning (mpreiss9 method)
For items without calculation parents, EdgarTools scans the statement from bottom to top, using subtotals as section boundaries:
Total Current Assets ← Defines boundary for "Current Assets" section
↑
All items above until next subtotal belong to "Current Assets"
↑
Property, Plant & Equipment ← This item gets assigned "Current Assets"
section based on its position relative to subtotal
Passing Context to the Mapper
When calling the mapper directly, you can provide context for disambiguation:
mapper = get_default_mapper()
# Provide context for accurate disambiguation
label = mapper.map_concept(
"us-gaap_OtherAssetsNoncurrent",
"Other Assets",
{
"statement_type": "BalanceSheet",
"section": "Non-Current Assets", # Helps resolve operating vs non-operating
"calculation_parent": "us-gaap:AssetsNoncurrent",
"level": 2,
"is_total": False
}
)
