[0010] Devices deployed for a particular service (e.g., home automation, environmental sensing, etc) may be specifically configured to implement the functions of the particular service. However, re-purposing the devices for another service after deployment may be difficult.

[0011] Examples described herein provide an approach to implement a service via a service agreement. For example, an electronic device may include a processor. The processor may receive, from an intent publishing device, a resource agreement associated with a service to be implemented via the intent publishing device. The processor may also transmit the resource agreement to a claiming device. The processor may further receive a confirmation from the claiming device, where the confirmation is to indicate that the claiming device is to implement the resource agreement The processor may further match the intent publishing device with the claiming device based on the confirmation. In this manner, examples described herein may reduce difficulty associated with re-purposing a device for different services.

[0012] FIG. 1 illustrates a system 100 to implement a service via a resource agreement, according to an example. System 100 may include an intent publishing device 102, a host 104, and a claiming device 106. Each of intent publishing device 102, host 104, and claiming device 106 may be implemented using an electronic device, such as , a web-based server, a local area network server, a cloud-based server, a notebook computer, a desktop computer, an all-in-one system, a tablet computing device, a mobile phone, an electronic book reader, an appliance, a wearable electronic device, etc. Each of intent publishing device 102, host 104, and claiming device 106 may include a processor 108. 110, 112 to control operations of the corresponding device, respectively.

[0013] During operation, intent publishing device 102 may transmit a resource agreement (RA) 114 to host 104. RA 114 may be associated with a service that intent publishing device 102 is to implement. RA 114 may indicate a resource to be used to implement the service. The resource may be a hardware component, processor executable instructions, or a combination thereof; For example, a resource may be a camera, a sensor, a touch-sensitive display, a compass, an accelerometer, an operating system, an email client application, an Internet browser application, etc. in an example, intent publishing device 102 may implement a weather forecasting service. RA 114 may indicate that a device is to have a temperature or humidity sensor to collect data. As another example, RA 114 may indicate that a device is to have a display to present the weather forecasting data. Although one RA is shown in FIG. 1, it should be understood a particular service may have any number of RAs.

[0014] In response to a request from claiming device 106, host 104 may transmit RA 114 to claiming device 106. Claiming device 106 may determine whether claiming device 106 is to implement RA 114 (i.e., provide the resource indicated in RA 114). When claiming device 106 is to implement RA 114, claiming device 106 may transmit a confirmation 116 to host 104. Confirmation 116 may indicate that claiming device 106 is to implement RA 114.

[0015] in response to receiving confirmation 116, host 104 may match intent publishing device 102 with claiming device 106 so that claiming device 106 may provide the resource to intent publishing device 102 to implement the service. For example, host 104 may transmit identification information 118 of claiming device 106 to intent publishing device 102. Based on identification Information 118, intent publishing device 102 may communicate with claiming device 106 to receive the resource. Identification information 118 may be an Internet protocol (IP) address of ciaiming device 106, a media access control (MAC) address of claiming device 106, or any other information that enables another device to communicate with claiming device 106.

[0016] As another example, host 104 may transmit identification information 120 of intent publishing device 102 to claiming device 106. Based on

identification information 120, claiming device 106 may communicate with intent publishing device 102 to provide the resource. Identification information 120 may be an IP address of intent publishing device 102, a MAC address of intent publishing device 102, or any other information that enables another device to communicate with intent publishing device 102.

[0017] in some examples, the roles of intent publishing device 102, host 104, and/or claiming device 106 can change depending on the communication network, the type of service to be implemented, etc. For example, host 104 may be an intent publishing device in another communication network. Claiming device 106 may be an intent publishing device associated with a second service and intent publishing device 102 may be a claiming device associated with the second service.

[0018] FIG. 2 illustrates a message flow between an intent publishing device and a host to publish a resource agreement, according to an example. Before intent publishing device 102 transmits RA 114 to host 104, host 104 is to authenticate intent publishing device 102 for security purpose. Intent publishing device 102 may transmit a publishing request 202 to host 104. Publishing request 202 may include information associated with intent publishing device 102 that is to be used for authentication. For example, publishing request 202 may include a user name and a password. As another example, publishing request 202 may include identification information 118.

[0019] In response to receiving publishing request 202, host 104 may authenticate intent publishing device 102 based on publishing request 202. In some examples, host 104 may authenticate intent publishing device 102 locally, in some examples, host 104 may authenticate intent publishing device 102 via an authentication server (not shown in FIG. 2). In response to a successful authentication, host 104 may transmit an authentication message 204 to intent publishing device 102. Authentication message 204 may indicate that intent publishing device 102 is authenticated and has permission to publish any RAs to host 104. In response to receiving authentication message 204, intent publishing device 102 may transmit a service request 206 and RA 114 associated with service request 206 to host 104. Service request 206 may describe what service intent publishing device 102 is to implement and indicate RA(s) associated with the service. [0020] FIG. 3 illustrates a message flow between a host and a claiming device to implement a resource agreement, according to an example. During operation, host 104 may generate a service catalog 302 that describes a list of services that are to be implemented by different intent publishing devices. Host 104 may transmit service catalog 302 to claiming device 106 (e.g., via

broadcasting). Claiming device 106 may examine service catalog 302 to determine if any service from service catalog 302 is of interest. Claiming device 106 may transmit a request 304 to host 104 to request RA(s) associated with a particular service. Based on request 304, host 104 may transmit RA 114 to claiming device 106. Claiming device 106 may transmit confirmation 116 to host 104 to claim RA 114.

Thus, computer-readable storage medium 404 may be, for example, Random Access Memory (RAM), an

Electrically Erasable Programmable Read-Only Memory (EEPROM), a storage device, an optical disc, etc. In some examples, computer-readable storage medium 404 may be a non-transitory storage medium, where the term

For example, referring to FIG. 1 , in response to a request from claiming device 106, host 104 may transmit RA 114 to claiming device 106. Confirmation receiving instructions 412 may receive a confirmation from a claiming device to indicate that the claiming device is to implement a received RA. For example, referring to FIG. 1 , host 104 may receive

confirmation 116 from claiming device 106 when claiming device 106 is to implement RA 114. Intent publishing device and claiming device matching instructions 414 may match an intent publishing device and a claiming device to enable communication between the intent publishing device and the claiming device. For example, referring to FIG. 1, host 104 may transmit identification information 118 of claiming device 106 to intent publishing device 102 to match claiming device 106 with intent publishing device 102. As another example, host 104 may transmit identification information 120 of intent publishing device 102 to claiming device 106 to match claiming device 106 with intent publishing device 102.
