What the data for this category looks like
Data sources include industry research reports published by property management industry associations, monthly operation ledgers of managed projects, standardized service manuals of property enterprises, public area energy consumption monitoring reports, and property asset survey data commissioned by financial institutions. Update frequencies vary: industry research reports are updated monthly, project operation data is updated weekly, and financial institution commissioned survey data is updated on demand. Document length varies widely, ranging from single-project inspection records (several pages) to large park annual format analysis reports (dozens of pages). Document fields include project number, format type, energy consumption value, service response duration, compliance check item status, associated building ID, owner feedback tags, and more. The unit for energy consumption value is kilowatt-hours per square meter, and the unit for service response duration is minutes.
What constraints these characteristics impose on HTTP interfaces and external systems
Multiple data sources require the interface to support integration with multiple external systems, including industry association APIs, property ERP systems, energy consumption monitoring databases, and financial institution survey data interfaces. The wide range of document lengths requires the interface's context recall parameters to support dynamic adjustment, and the parsing module to adapt to documents of different lengths. Fields with specific units require the interface to perform unit validation on returned fields to avoid data misuse. Differences in update frequencies require external system synchronization tasks to support configuring different cycles based on data type, pulling weekly, monthly, and on-demand updated data separately. Project and organization-level associated fields require the interface to carry project and organization permission parameters to ensure that only research report data for the corresponding entity is returned.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
RETRIEVE_TOP_K | 3-8 entries | Property management research reports contain precise information about specific formats. Too many recalls will introduce irrelevant non-format data, while too few will fail to cover all scenario requirements |
PARSE_FILE_TIMEOUT_SECONDS | 300-600 seconds | A single large park annual research report may exceed 50 pages, so parsing large files requires a longer timeout period |
HTTP_REQUEST_TIMEOUT | 120 seconds | When pulling batch project data by connecting to the property ERP system, a longer response duration must be matched |
SYNC_INCREMENTAL_INTERVAL | Weekly, monthly, and on-demand three configurations | Operation data is updated weekly, industry research reports are updated monthly, and financial institution commissioned survey data is updated on demand. Different synchronization cycles must be set based on data type |
FIELD_UNIT_CHECK | Enabled | Fields such as energy consumption and duration in property management research reports have specific units, so returned value units must be validated against preset rules |
MAX_REQ_BODY_SIZE | 100 MB | Some large park annual energy consumption summary documents have large file sizes, so large request body uploads must be supported |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require specific analysis, and it is recommended to test on your own samples before finalizing.
Three common mistakes
- Phenomenon: The energy consumption field returned by the interface does not include the
kilowatt-hours per square meterunit, or the unit is incorrectly converted tokWh. Cause: TheFIELD_UNIT_CHECKconfiguration is not enabled, and no unit validation is performed on fields returned by external systems. - Phenomenon: A
504 Gateway Timeoutstatus code is returned when calling the external ERP interface to pull data. Cause: The setHTTP_REQUEST_TIMEOUTvalue is less than 120 seconds, which does not match the response duration required for batch project data pulling. - Phenomenon: Incremental synchronization fails to pull monthly updated industry research reports, resulting in missing latest industry analysis data in retrieval results. Cause: Multi-cycle synchronization rules are not configured, and only a unified synchronization interval parameter is set.
How to confirm the configuration is correct
- Call the test interface with the project identifier of a specified format, and check if the returned data fields include the corresponding format identifier.
- Upload a single research report document with more than 40 pages, and confirm that the parsing task does not trigger a timeout error.
- View the external system synchronization logs, and confirm that weekly, monthly, and on-demand data sources are pulled according to their respective cycles.
- Pass test parameters that do not match preset units, and confirm that the interface returns a prompt indicating format verification failure.
