We have received a lot of feedback on this. We are looking at on-line help with better samples of queries and responses. We are looking at some web frameworks for offering a live “Try It” feature for PI Web API. We are also looking at comprehensive search within the PI Web API help system.

Looking for more inputs on how to determine what the last good value is (was). While it’s simple to say a numeric value is good, but what if it’s a non-sensical numeric value like 1000 for temperature? It is also possible to the source system to send out status like NoData. How should that be interpreted? Please provide your inputs.

@stephen, I just want it to tell me the last entry that isn't a SYSTEM digital state. I'll handle any weird unique data issues.

We have started development on Community Management features and Stream data sharing in OSIsoft Cloud Services (OCS) to enable sharing of operational data across tenants.
As part of the Community creation workflow, we are working on a way that Communities are formed without exposing other customer accounts/tenants in the process.
Additionally, Namespaces can now be used to segregate customer data (if you’re providing a service to those customers), or the data can be stored in their own OCS tenant/account and then shared via Community data sharing functionality (when it becomes available).

If you have an active use case where you are trying to share data with external business partners of yours and you interested in trying this out once we have reached a point in our development where this is possible, please let us know and we will add you to our list!

I feel the pain! For those interested (and those not afraid to break the rule of not querying PIFD directly!) I came up with a SQL query you can run against PIFD. You copy your PI tag name into line 3 and it searches the SQL database for everywhere it's referenced. So far it's proven reliable. The way it's written it only searches one tag a time - I'm sure it's possible to search multiple.
-- Paste your PI Point name in the 'SET' line. It has to be exact.
DECLARE @PIPoint VARCHAR(MAX)
SET @PIPoint = 'RAWHIDPT.Cryo Unit.NGL.C2Rec (Simulated)'-- Do not modify anything below this
SELECT
ep.path As 'Element Path',
ep.name As Element,
ta.path AS 'Attribute Path',
ta.name As Attribute,
adr.configstring,
'Yes' As Template,
CASE WHEN ta.fkparentattributeid IS NOT NULL THEN 'Yes' ELSE 'No' END As 'Is Child Attribute'
FROM AFElementAttributeDR adr
INNER JOIN AFElementTemplateAttribute ta on ta.rid = adr.fkattributetemplateid
INNER JOIN AFElementVersion ev on ev.rid = adr.fkelementversionid
INNER Join afelementpathA0 ep on ep.elementversionid = ev.id
WHERE adr.fkattributetemplateid IS NOT NULL
AND ep.primarypath = 1
AND adr.configstring like '%\' + @PIPoint + '?%'UNION

In System Explorer (or Excel for that matter) you should be able to search for attributes based on the Config String. This would come in handy a number of ways. Primarily, if we have a PI tag being written to from two places, you can bet one is analytics. So it would be nice to search AF for where that PI tag is mapped. Right now to do that you would have to dump the entire AF to excel and search for it; not feasible at scale.
PLEASE!!! The user experience of having to grab the scroll bar at the bottom atrocious!
