  1. Expose UOM Groups in PI Web API

    As a programmer I want the PI Web API to expose an endpoint for reading UOM Groups and UOM Group mappings. This would allow javascript based web applications to read the UOM Groups and mappings in order to use the mappings in subsequent data stream requests. Then the end users could see all data in familiar UOMs according to their selected UOM Group.

    UOM Groups was introduced in PI AF 2017 R2 and is supported in AF SDK 2.9.5+.

    The endpoint could e.g. be at
    https://host/piwebapi/assetservers/{assetServerId}/uomgroups/ and https://host/piwebapi/assetservers/{assetServerId}/uomgroups/{groupId}/mappings/

    A similar request exist under PI Vision product and maybe they can…

  2. Add element reference information to to RTQP tables.

    In OLEDB Enterprise, we could find element references by type.  Currently, this information is not exposed in RTQP.  It would be helpful to be able to identify which type of reference an element is using.  One use case is for PI Admin's to generate reports on element hierarchy to ensure the proper reference is being used by builders of the AF DB.  This is especially helpful in AF DBs where element references are used to build multiple "views" using the same elements and the reference type could be used in conjunction with the new IsPrimaryPath column for reporting.

  3. Don't install SQL Commander Lite with OLEDB Drivers Automatically

    We did install the SQL Client software on our SQL server, but there was no option to exclude the SQL Commander Lite. So, we had to turn around and uninstall SQL Commander Lite. I'd just like to suggest for future install packages that there be an option to exclude SQL Commander Lite.

  4. Write annotations on archive data via PI Web API

    My client is interested in writing annotations to Stream (time series) data via the PI Web API. I know it's possible to pull this data via the ?associations=annotations query parameters but the write feature is missing.

  5. Expose Event Frame Annotations in PI SQL DAS (RTQP Engine)

  6. Add Annotations support for RTQP Engine

    I would like the RTQP Engine to be able to read annotations.
    My use case is the following :
    I have user that enter manual values into PI along with these values the operator will specify the reason for this manual input.

    The comment is stored in an annotations, there is currently no way to retrieve this information.

    Retrieving a string would be sufficient for my needs.

  7. PI ODBC driver for linus

    There is a pi JDBC driver for linux, but not an ODBC driver. This means that tools built around ODBC do not fully exploit the tools functionality. For example, RStudio has great database navigation tools that require ODBC.

  8. Missing Open API (Swagger) specification for the Search controller

    The swagger specs for the search controller are not available. This will be useful in the client libs for searching

  9. Support DST Transition on Second Granularity in PI SDK

    A user tries to retrieve date with timestamp 03-Nov-2018 23:59:59 (1 second before Daylight Saving Time beginning) in PI SMT, but the returned event has a timestamp of 04-Nov-2018 00:59:59. This is because PISDK timezone design is such that it can only transition DST on minute granularity, and the Windows TZ info for Brazil says the transition is at 23:59:59 so PISDK truncates the seconds for the transition rule.

  10. Have Status of an analysis

    I would like to have status of analysis (Enabled, Disabled, Running, Error or Warning) via PI AF SDK with the attribute 'Status' or the method 'GetStatus'.
    In the library, we already have in AFStatus all the Status declared but not used.

    Thanks to that it will be possible to see all analysis in error and try to resolve analysis in error with AF SDK.
    Morever, We won't do backfilling on analysis in error and create other error, it will be clean to do backfilling on all analysis Enabled if we know which analysis are in error.

    Sorry for my english…

  11. Reset Attribute to Template method in PI Web API

    Synced to PI Square at https://pisquare.osisoft.com/ideas/29447

    As a developer using PI Web API, I would like to have a Reset an attribute to template method using the Web API so I can program with greater flexibility.

    I am attempting to create a .NET Core App and this limitation prevents us from using PI Web API exclusively in automated AF Builds

  12. Add more date and time functions to PI SQL Client

    As a PI SQL Client OLEDB user, I would like to have the TIME(), DATE(), LOCALDATE() and TOLOCALDATE() functions available in order to construct datetimes for my queries.

    These functions were available in PI OLEDB Enterprise, but are not available in PI SQL Client OLEDB.

  13. Add support for AFElement Versions

    Add support for AFElement versions to PI Web API.
    1. Create a new Element Version by defining the effective date and an optional version comment. 2. Add Get and Find methods which support querying AFElements by setting a QueryDate.

  14. Provide programmatic interface to manage OMF applications

    Enable Create,Read, Update, Delete operations for OMF applications via an API so that the process is standardized and efficient/effective as opposed to manual and error prone, especially for larger numbers of apps.

  15. AF SDK and Web API on Linux OS'es

    With Microsoft supporting .NET Core on Linux operating systems such as RHEL, SLES Ubuntu, CentOS, and Debian.
    https://docs.microsoft.com/en-us/dotnet/core/about
    https://docs.microsoft.com/en-us/dotnet/core/linux-prerequisites?tabs=netcore2x

    They are even supporting SQL Server on Linux OS'es.

    I don't know the dependencies of the AF SDK nor the Web API, but if they can use .NET Core; it would be nice to have the AF SDK and Web API available for Linux based OS'es.

  16. Option to verify PI Data Archive connection during PI SDK installation

    During PI SDK installation, there is currently no option to verify the connection to the PI Data Archive. This can lead to complications if, for example, PI Interface Configuration Utility (which includes PI SDK) is the first piece of PI software installed on the machine and an invalid PI Data Archive name has been entered during the installation. Because there is no verification in the installer, the PI SDK and anything that relies on the Known Servers table entry such as interface.bat files must be corrected post-installation.

  17. Schedule PI Web API Crawls

    The customer would like the ability to schedule crawls for a specific AF database (it's quite large), so that crawls don't interrupt users who need to access the elements in the PI Vision search during their working hours.

  18. Return Partial Results From Event Frame Search in PI Web API

    Currently when searching for event frames, a 400 error is returned if not all elements in the search exist.

    piwebapi/eventFrames/search?databaseWebId=WebId&Element:IN("\\server\AssetSwap\Site2\Asset1";"\\server\AssetSwap\Site2\Asset2"

    This is cumbersome especially in the case of asset swapping in PI Vision when parent elements could contain variable child elements. For any parent element that contains less than the max child elements, a 400 error will occur when searching for event frames for related parent elements.

  19. Add support for AFFile type

    To support reading/writing files stored in AF. Read is more important though.
    Started from here: https://pisquare.osisoft.com/thread/37635-access-pdftextdoc-files-from-af-server

    I want to be able to use AF as a one-stop place to access my Asset Data. Therefore i want to be able to access Files stored in AF to provide this data alongside all other data through the PI Web API.

  20. Powershell - Add the ability to get Attributes or Elements by Category

    Add the ability to retrieve Attributes and Elements by category for Powewhell command-lets.

    Example 1:
