Object Structures

  • /maximo/oslc/os/mxapiasset?attributesearch=[SPEED:>=50;AREA;ELEV:=300]
    • Classification attribute search.
  • /maximo/oslc/jsonschema/<object structure>
    • GET jsonschema/mxapiwodetail – gets the schema for the OS, but one object at a time.
    • GET jsonschema/mxapiwodetail?oslc.select=* - gets the full schema
    • Support child object schemas GET jsonschema/mxapiasset/assetmeter
    • Support schema views - Get jsonschema/mxapiasset?oslc.select=attr1,rel1.attr2

Headers

Key Value Description
maxauth=base64(username:password) required Username and Password encoded as base64
Content-Type=application/json - -
Accept=application/json - -
properties=*
properties=attr1,attr2
usado no POST Usar o header de properties elimina a necessidade de fazer um GET extra após um create ou update
x-method-override: PATCH usado no POST informa ao servidor que será um update
x-method-override: PATCH
patchtype: MERGE
usado no POST informa ao servidor que será um update e atualiza os filhos

Parameters

Key Description
uri?lean=1 simple notation
uri?oslc.select especifica o conjunto de atributos a serem buscados nas estruturas de objetos, bem como nos objetos relacionados. Veja seção os.select abaixo.
uri/<os>?distinct=attr1&oslc.where=... select DISTINCT Ex: site /os/mxapiasset?distinct=siteid&oslc.where=...
uri?oslc.where especifica a cláusula WHERE para filtrar o conjunto de resultados de uma consulta. Veja seção oslc.where abaixo.
uri?oslc.orderBy
uri?oslc.orderBy=-attr1,+attr2
especifica como os resultados de uma consulta são ordenados. O sinal de (-) para ordem decrescente e sinal de (+) para ordem crescente, sendo que o sinal + deve estar encoded.
uri?oslc.paging=true -
uri?oslc.pageSize=N
uri?oslc.pageSize=N&stablepaging=true

especifica os recursos para cada página de uma consulta.

  • Stable Paging – good for downloading large data sets.
  • Auto paging – Helps prevent OOM for large dataset requests when no page size specified. Default 1000 records
  • Limit Paging – Helps prevent OOM for large dataset requests when high page size specified.
    • mxe.oslc.maxpagesize: define o valor para todos as Object Structures
    • mxe.oslc.<os name in lower case>.maxpagesize: define o valor para uma Object Structures, sobrepõe mxe.oslc.maxpagesize
uri?savedQuery=name Saved query can be SQL, Java, Auto Script. /apimeta/<os name> lists all saved queries for an Object Structure
uri?actions=name veja seção Actions abaixo
uri?tlrange=-3M&tlattribute=dateattr[=indexdate]
  • tlattribute - the timeline attribute to which the range applies. If no index data specified, its defaulted to the current date-time.
  • tlrange – The range in Months (M)/Years (Y)/ Week (W)/ Days (D)/ Hour (h)/Min (m)/ Seconds (s). + and - indicates whether to add or substract from tlattribute date-time.
POST uri?interactive=1 Handling Yes/No/Cancel interactions
GET uri?gbcols=status,count.*,sum.attr1&gbsortby=-count.*

Aggregation APIs. Also supports date histograms – yearly/quarterly/monthly/weekly.
For example:
GET /mxapiwodetail? gbcols=year$statusdate,quarter$statusdate,sum.actlabhrs

uri?collectioncount=1 retorna o totalCount e totalPages na reposta
Set mxe.oslc.collectioncount system property to 1, the totalCount and totalPages parameters are included by default as part of the responseInfo.
uri?count=1 only the total count of records that match the query and not the records
uri?_dropnulls=0 To force the response to add null value attributes, API response skips the null value attributes by default
uri?_format=xml
uri?_format=csv
type of output


OSLC.SELECT

Key Description
oslc.select=assetnum,locationmylocation Apelido para atributo, para resolver conflitos de mesmo nome. Senão adicionado retorna $alias_this_attr$
oslc.select=attr1,attr2,child{attr4,attr5,grandchild{*}} -
oslc.select=attr1,rel1.attr1,rel.rel2{attr1,attr2},rel.rel3.os {*}
  • rel1.attr1 – 1:1 relations. Results in a JSON Object for property named “rel1”.
  • rel.rel2 {attr1,attr2} – 1:* relations. Results in a JSON Array for property named “rel2”.
  • rel.rel3.os {*} – 1:* relations. Results in a JSON Array with OS json (for the named os) as array members.
/oslc/os/mxasset?oslc.select=assetnum,status,exp.myreplacecost

create a object formula called MYREPLACECOST for asset object by using the Object Formula action in the Database Configuration application. The formula is purchaseprice/NVL(priority,1).

/oslc/os/mxasset/{id}?oslc.select=assetnum,openwo.actlabhrs._dbmax, ...

database aggregation (max,min,avg,sum,count, and exists) functions on related MboSets, must add _db prefix.

oslc.select=assetnum,status&internalvalues=1

Domain internal values. Returns as <attribute name>_maxvalue property.

OSLC.WHERE

Key Description
uri?oslc.where=attr1 in ["val1","val2"] and attr2>200 -
uri?oslc.where=status in ["OPERATING","ACTIVE"] and priority=3 and statusdate>"ISO date string" and linear=false -
uri?oslc.where=objectname IN ["WORKORDER","WOACTIVITY] -
uri?oslc.where=priority in [1,2,3] -
uri?oslc.where=status="%APPR%" like "%APPR%", aceita também "APPR%" e "%APPR"
uri?oslc.where=status="*" status is not null
uri?oslc.where=status!="*" status is null
uri?oslc.where=usewith="INTEGRATION" -

ACTIONS

Key Description
uri/<os>/{id}?action=wsmethod:changeStatus

Chama actions. Exemplo:

POST /maximo/oslc/os/mxasset/{id}?action=wsmethod:changeStatus
{
 "rollToAllChildren": true,
 "removeFromActiveSP": true,
 "removeFromActiveRoutes": true,
 "status": "string",
 "changePMStatus": true
} 
uri/<os>/{id}?action=workflow:<workflow name>

This invokes the named workflow in the context of the MBO that is identified in the URI.

POST uri/<os>/{id}?action=workflow:<workflow name>
X-method-override: PATCH
