Open Scalable Request Framework (OpenSRF), pronounced ¡°open surf¡± is a message routing network that offers scalability and failover support for individual services and entire servers with minimal development and deployment overhead. You can use OpenSRF to build loosely-coupled applications that can be deployed on a single server or on clusters of geographically distributed servers using the same code and minimal configuration changes.

Developing on OpenSRF
Dan Scott has written a two part article which is a detailed introduction to OpenSRF.? “This article introduces OpenSRF, how to build OpenSRF services through code examples, explains the technical foundations on which OpenSRF is built, and evaluates OpenSRF¡¯s value in the context of Evergreen” – “Easing gently into OpenSRF, Part 1” and “Easing gently into OpenSRF, Part 2“.
He also has an introductory workshop available along with some Perl/JavaScript examples – “Evergreen development“.
A Gitweb instance sits atop the Git repository for OpenSRF and is available at?git.evergreen-ils.org. Here is the running change log for the OpenSRF code repository:?watch us work.
Trac sends code commits to public OpenSRF commits mailing lists:

He spurted a pint to reply, "Fishe's batt'ry." One evening Arthur Withers and Rose Lomas sat together on their favourite stile talking in low whispers. The summer dusk lagged, and the air about them was so still that between their softly spoken words they could hear the talk of innumerable insects in the grass at their feet. There had been few interruptions. So familiar had their figures become in that position, that it had grown to be almost a tradition among the people who passed that way during the evening to cross the stile without disturbing the lovers. There are ways, too, of sitting upon a stile without incommoding the casual pedestrian. "That is a very fair question," Lawrence admitted. For disadvantages there is, on the other hand, a want of uniformity in fittings that prevents their interchange from one part of a line shaft to the other¡ªa matter of great importance, as such exchanges are frequently required. A line shaft, when constructed with pieces of varying diameter, is special machinery, adapted to some particular place or duty, and not a standard product that can be regularly manufactured as a staple article by machinists, and thus afforded at a low price. Pulleys, wheels, bearings, and couplings have all to be specially prepared; and in case of a change, or the extension of lines of shafting, cause annoyance, and frequently no little expense, which may all be avoided by having shafts of uniform diameter. The bearings, besides being of varied strength and proportions, are generally in such cases placed at irregular intervals, and the lengths of the different sections of the shaft are sometimes varied to suit their diameter. With line shafts of uniform diameter, everything pertaining to the shaft¡ªsuch as hangers, couplings, pulleys, and bearings¡ªis interchangeable; the pulleys, wheels, bearings, or hangers can be placed at pleasure, or changed from one part of the shaft to another, or from [47] one part of the works to another, as occasion may require. The first cost of a line of shafting of uniform diameter, strong enough for a particular duty, is generally less than that of a shaft consisting of sections varying in size. This may at first seem strange, but a computation of the number of supports required, with the expense of special fitting, will in nearly all cases show a saving. That same Friday evening the women and children living in the Rue de la Station were told to leave their houses as the whole street was to be burned down. Everybody fled, but the design was not executed. The burgomaster and his son were taken prisoners, and brought to Tongres; later on the son was released; the Very Reverend the Dean was also arrested. In one of the alleys by the outer wall was a little house with a door in carved panels framing[Pg 243] inlaid work as delicate as woven damask. A crowd surrounding it could not be persuaded by Abibulla's eloquence to make way for me, a suspicious-looking stranger. ¡°It will do no harm to go over,¡± agreed Mr. Whiteside, slamming the door behind them. ¡°It¡¯s shorter down along the water.¡± "No 1 in the front rank will face to the right, and stand fast, and take a side step to the right. Each No. 2 will face to the right, and take on oblique side step to the right to place himself on the right hand of his No. 1 man." While Si was going back the way he had come Shorty was tearing through the tangled brush, turning over the tree-tops by main strength, searching for Pete Skidmore. The rest of the company were seeking out the fallen ones hither and thither, and calling to one another, as they made discoveries, but Shorty only looked for Pete Skidmore. Si and Harry presently came to Gid Mackall's body, lying motionless in a pool of blood that dyed crimson the brown leaves thickly covering the ground. His cap had fallen off, and his head had crushed down into a bunch of slender oak twigs; his eyes were closed, and his callow face white as paper. Harry looked up from his plate, and the gaze became three-cornered. Reuben, defiant of his brother, grew bold, and ogled, whereupon Naomi grew timid, and dropped her eyes; Harry found himself speaking with a rasp: In the kitchen a substantial meal was prepared. It was the children's supper, and was to last Reuben till he came in at nine o'clock and had a bowl of broth before going to bed. Old Mrs. Backfield was settling the children round the table. Caro and Tilly showed only their heads above the cloth, a piece of neck proclaimed Benjamin's extra inches, while Richard had quite two buttons to his credit. Harry sat at the bottom beside Caroline; when he heard Albert's rattle, he seized it and began making a hideous din. Caro and Tilly began to cry, and Reuben snatched the rattle away. Chapter 16 The year passed, and the new year came, showing the farm still on the upward struggle, with everyone hard at work, and no one, except Reuben, enjoying it particularly. Luck again favoured Odiam¡ªthe lambing of that spring was the best for years, and as the days grew longer the furrows bloomed with tender green sproutings, and hopes of another good harvest ran high. "It was not becoming that I should use my fists, except to defend the weak. I am a minister of the Lord." HoME²¨¶àÒ°½áÒÂHͼ
