When a user wishes to open, create, or edit a document in an online application hosted by the online application server, the interface server is called, instead of the IM server which manages the document at the backend of an enterprise computing network. The interface server is configured for obtaining a working copy of the document from the IM server and providing the working copy to the client. The client provides the working copy to the online application for display on the user device. When the work is done, the working copy is sync'd back through the interface server to the IM server as a new draft and deleted by the interface server. ## Claims ### Claim 1 A method, comprising: receiving, from a user device by an interface server, a request to open or create a document in an online application hosted by an online application server, the document managed or to be managed by an information management (IM) server operating in an enterprise computing environment; performing, by the interface server, a discovery process to learn from the IM server operating in the enterprise computing environment a set of parameters needed to open or create the document in the online application hosted by the online application server; providing, by the interface server, the set of parameters learned from the IM server operating in the enterprise computing environment to the online application server; receiving, by the interface server from the online application server, a call with the set of parameters requesting the document from the IM server operating in the enterprise computing environment; communicating, by the interface server, the call from the online application server to the IM server operating in the enterprise computing environment, wherein the IM server fetches or creates the document in the enterprise computing environment, makes a copy of the document, and communicates the copy of the document to the interface server; receiving, by the interface server, the copy of the document from the IM server operating in the enterprise computing environment; and caching, by the interface server, the copy of the document for the online application server in a local data storage, wherein the online application server operates to display the copy of the document on the user device via the online application hosted by the online application server. ### Claim 2 (depends on 1) The method according to claim 1, wherein the request to open or create the document is received from an IM application and comprises a document identifier for the document and a bearer token, wherein the IM application is a client of the IM server operating in the enterprise computing environment. ### Claim 3 (depends on 1) The method according to claim 1, further comprising: syncing, by the interface server, the copy of the document to reflect any update to the document; and locking, by the interface server, the copy until an unlock request is received or until a timeout condition is met. ### Claim 4 (depends on 1) The method according to claim 1, further comprising: prior to the communicating, determining, by the interface server, whether the document is locked; and responsive to the document being locked, hosting an existing copy of the document for the online application server. ### Claim 5 (depends on 1) The method according to claim 1, further comprising: pulling, by the interface server at a predetermined interval, the online application server for updates to the document. ### Claim 6 (depends on 1) The method according to claim 1, further comprising: receiving, by the interface server, updates or whole files from the online application server. ### Claim 7 (depends on 1) The method according to claim 1, further comprising: syncing, by the interface server, the copy of the document to the IM server operating in the enterprise computing environment for creating a new object; and deleting, by the interface server, the copy of the document from the local data storage. ### Claim 8 A system, comprising: a processor; a non-transitory computer-readable medium; and stored instructions translatable by the processor for: receiving, from a user device, a request to open or create a document in an online application hosted by an online application server, the document managed or to be managed by an information management (IM) server operating in an enterprise computing environment; performing a discovery process to learn from the IM server operating in the enterprise computing environment a set of parameters needed to open or create the document in the online application hosted by the online application server; providing the set of parameters learned from the IM server operating in the enterprise computing environment to the online application server; receiving, from the online application server, a call with the set of parameters requesting the document from the IM server operating in the enterprise computing environment; communicating the call from the online application server to the IM server operating in the enterprise computing environment, wherein the IM server fetches or creates the document in the enterprise computing environment, makes a copy of the document, and communicates the copy of the document to the system; receiving the copy of the document from the IM server operating in the enterprise computing environment; and caching the copy of the document for the online application server in a local data storage, wherein the online application server operates to display the copy of the document on the user device via the online application hosted by the online application server. ### Claim 9 (depends on 8) The system of claim 8, wherein the request to open or create the document is received from an IM application and comprises a document identifier for the document and a bearer token, wherein the IM application is a client of the IM server operating in the enterprise computing environment. ### Claim 10 (depends on 8) The system of claim 8, wherein the stored instructions are further translatable by the processor for: syncing the copy of the document to reflect any update to the document; and locking the copy until an unlock request is received or until a timeout condition is met. ### Claim 11 (depends on 8) The system of claim 8, wherein the stored instructions are further translatable by the processor for: prior to the communicating, determining whether the document is locked; and responsive to the document being locked, hosting an existing copy of the document for the online application server. ### Claim 12 (depends on 8) The system of claim 8, wherein the stored instructions are further translatable by the processor for: pulling, at a predetermined interval, the online application server for updates to the document. ### Claim 13 (depends on 8) The system of claim 8, wherein the stored instructions are further translatable by the processor for: receiving updates or whole files from the online application server. ### Claim 14 (depends on 8) The system of claim 8, wherein the stored instructions are further translatable by the processor for: syncing the copy of the document to the IM server operating in the enterprise computing environment for creating a new object; and deleting the copy of the document from the local data storage. ### Claim 15 A computer program product comprising a non-transitory computer-readable medium storing instructions translatable by a processor of an interface server for: receiving, from a user device, a request to open or create a document in an online application hosted by an online application server, the document managed or to be managed by an information management (IM) server operating in an enterprise computing environment;
